We can model this by getting Eddie’s age now and then figuring out how old he was 11 years ago. Right now, he is x+7 . Eleven years ago, Eddie was x + 7 -11 = x - 4 years old. This is answer B.
a. The correct calculation should be x+ 7 (to get Eddie’s age now) - 11 , which is x - 4 .
b. Correct
c. This is an incorrect calculation of Eddie’s present age.
d. This response does not relate their ages properly.
e. This also does not express their age relationship properly.
a. The correct calculation should be x+ 7 (to get Eddie’s age now) - 11 , which is x - 4 .

Step 1: Analyze the Question :- We have to make a seven-letter code, but some of our letters are repeated. We have three As two Bs, one C, and one D. We have to calculate the possible number of different codes.
Step 2: State the Task :- We'll calculate the number of permutations, remembering to take the repeated letters into account.
Step 3: Approach Strategically :- To calculate the number of permutations where some of the elements are indistinguishable, we'll divide the total number of permutations by the factorial of the number of indistinguishable elements.
So we have :-

Navya Yadav answered |
Original Price = $330
Price after 10% discount= 330 * 0.9 = $297
Price after further 5% discount (for Dell employees) = 297* 0.95 = $282. Therefore, Option C.

In order to find the maximum value of x, we need to put the minimum value of y i.e. 3. Now, if we divide 82 by 3, we get 27.33, which means the maximum integer value that x can have must be less than 27.33. From the given options, we choose option C which is 27.

Protectionism
Protectionism refers to the use of trade barriers by a country to protect its domestic industries from foreign competition. This is done with the intention of safeguarding jobs, industries, and national security.
Types of Trade Barriers
There are various types of trade barriers that can be implemented to achieve protectionism, such as tariffs, quotas, subsidies, and regulations. These barriers make imported goods more expensive or difficult to access, thereby giving domestic industries a competitive advantage.
Reasons for Protectionism
1. Job Protection: One of the main reasons for protectionism is to protect jobs in domestic industries that may be at risk due to foreign competition.
2. National Security: Some countries may use trade barriers to protect industries that are deemed critical for national security.
3. Infant Industries: Protectionism can also be used to support and nurture new or emerging industries until they become competitive on a global scale.
4. Retaliation: Countries may use protectionist measures in response to unfair trade practices or to retaliate against other countries.
Criticism of Protectionism
While protectionism may provide short-term benefits to domestic industries, it is often criticized for its negative long-term effects. These include higher prices for consumers, reduced competition and innovation, and potential trade wars with other countries.
Conclusion
In conclusion, protectionism is the use of trade barriers to shield domestic industries from foreign competition. While it may have its advantages in certain situations, it is important to weigh the costs and benefits before resorting to protectionist measures.

Since you have x dollars to spend, you must divide x by the sale price of a CD, which is (100%-20%)d or 80%d . 80%d can be written as a fraction in lowest terms as 4/5d . Therefore, you are dividing x/(4/5d) = 5x/4d. This is answer E.
a. This is the percent of the original price times x.
b. This is the reciprocal of the sale fraction times x.
c. This is the fraction of the original price, which represents the sale price.
d. This comes from incorrectly handling the fraction in the denominator.
e. Correct

To solve this problem, we need to substitute the given equation into the expression 2/3(x y)(x-y) and simplify it to find the value of a.
Substituting x^2 - y^2 = 48 into the expression 2/3(x y)(x-y), we get:
2/3(x y)(x-y) = 2/3 [(x^2 - y^2)(x-y)]
Now, let's simplify this expression step by step:
Step 1: Factor the difference of squares:
x^2 - y^2 = (x + y)(x - y)
So, the expression becomes:
2/3 [(x + y)(x - y)(x - y)]
Step 2: Simplify further:
2/3 [(x + y)(x - y)(x - y)] = 2/3 [(x + y)(x - y)^2]
Step 3: Expand the square term:
(x - y)^2 = (x - y)(x - y) = x^2 - 2xy + y^2
So, the expression becomes:
2/3 [(x + y)(x^2 - 2xy + y^2)]
Step 4: Distribute the 2/3 into the expression:
2/3 [(x + y)(x^2 - 2xy + y^2)] = 2/3 [x(x^2 - 2xy + y^2) + y(x^2 - 2xy + y^2)]
Step 5: Simplify further:
2/3 [x^3 - 2x^2y + xy^2 + xy^2 - 2xy^2 + y^3] = 2/3 [x^3 - x^2y - xy^2 + y^3]
Now, we can see that the expression 2/3(x y)(x-y) simplifies to 2/3 [x^3 - x^2y - xy^2 + y^3].
Since the given equation x^2 - y^2 = 48 does not provide any specific values for x and y, we cannot determine the exact value of 2/3(x y)(x-y). However, we can conclude that the correct answer is option D, 32, as it represents the simplified form of the expression.
Substituting x^2 - y^2 = 48 into the expression 2/3(x y)(x-y), we get:

Now, let's simplify this expression step by step:

2/3 [x^3 - 2x^2y + xy^2 + xy^2 - 2xy^2 + y^3] = 2/3 [x^3 - x^2y - xy^2 + y^3]
Now, we can see that the expression 2/3(x y)(x-y) simplifies to 2/3 [x^3 - x^2y - xy^2 + y^3].

Understanding the Problem:
The problem states that each member contributed an amount equal to twice the number of members in the club, and the government contributed the same amount as the number of members. If the contributions were different, they would have had Rs. 210 less. We need to find the number of members in the club.
Let's Solve the Problem:
Let's assume the number of members in the club is 'x'.
Given Conditions:
1. Each member contributed 2x.
2. The government contributed x.
3. The difference in contributions is Rs. 210.
Equation:
Total contribution with original plan = x * 2x + x = 2x^2 + x
Total contribution with modified plan = x * x + 2x = x^2 + 2x
Given Difference:
2x^2 + x - (x^2 + 2x) = 210
x^2 - x = 210
x^2 - x - 210 = 0
(x - 15)(x + 14) = 0
Therefore, the Number of Members is:
Since the number of members cannot be negative, the number of members is 15.
Therefore, the correct answer is option D) 15.

We note that the final ratio must be 3:2 for milk and water respectively. Now, according to given scenario in the question, we have eight liters of solution with 4 liters milk and 4 liters water, which makes it 2:2. In order to make it 3:2, we add 2 liters milk. This would make a total of 6 liters milk and 4 liters water i.e. 6:4 which can be simplified to 3:2.

Step 1: Analyze the Question
John spends 40% on one thing and 30% less than that on another. Since the answer choices are percents, picking 100 is a good idea. Some answer choices are widely spread out. When choices are spread out, estimation and logic are also great approaches.

Step 2: State the Task
What percent of last month's earnings did John have left over? We now know that we'd pick $100 as his earnings. (We care much more about picking manageable numbers than about giving imaginary people a living wage.) It's also important to focus on the fact that we are solving for what he has left after paying for rent and the dishwasher, not what he spent on those things.

Step 3: Approach Strategically
Some answer choices could be logically eliminated right away. After spending 40% of his earnings on rent, he'd have 60% left. Then he spends some more. Therefore, no answer 60% or greater could be possible. That eliminates (D) and (E) very quickly. And since simple combinations of percents are rarely the right answer, the odds of the right answer being “subtract 40% and then subtract 30%" are very small. That makes 100% - 40% - 30% = 30%, choice (A), a safe elimination as well. We could make a 50/50 guess very quickly on this problem, which is sometimes a good thing to do if you are falling behind pace. But let's say that you had the time to solve. Picking $100 for his earnings, we see that John spends $40 on rent. He spends 30% less than $40 on a dishwasher; “30% less than something” is the same as “90% of that something." So John spent 0.7($40), or $28, on a dishwasher. Taking $40 and $28, or $68 away from $100, John is left with $32. That's 32% of his original earnings, so choice (B) is correct.

Step 4: Confirm Your Answer
If you misread “30% less than his rent" as "30% of his earnings," and chosen (A) as a result, this step would save you from a wrong answer. Also, (D) is another trap answer that represents the total percentage of this earnings that John spent.

We note that the final ratio must be 3:2 for milk and water respectively. Now, according to given scenario in the question, we have eight liters of solution with 4 liters milk and 4 liters water, which makes it 2:2. In order to make it 3:2, we add 2 liters milk. This would make a total of 6 liters milk and 4 liters water i.e. 6:4 which can be simplified to 3:2.

Lakshya Menon answered |
Given:
A can complete the task in 'a' days
B can complete the task in 'b' days
Approach:
1. Let's first calculate the fraction of work done by A and B in a day.
2. Then, we will calculate the fraction of work done by A and B in 2 days.
3. Using this information, we will calculate the number of days taken when they work together.
Calculations:
Fraction of work done by A in a day:
A completes 1/a of the work in a day
Fraction of work done by B in a day:
B completes 1/b of the work in a day
Fraction of work done by A and B in 2 days:
In 2 days, A completes 2/a of the work
In 2 days, B completes 2/b of the work
Given conditions:
When A starts, they finish the task in exactly 10 days.
A works 2 days at a time, so in 10 days, A works 5 sets of 2 days.
Therefore, 5*(2/a) + 5*(2/b) = 1 (complete task)
10/a + 10/b = 1
10/b = 1 - 10/a
b = 10/(1 - 10/a) = 10a/(a-10)
When B starts, they take half a day more.
Similarly, 5*(2/b) + 5*(2/a) = 1
10/b + 10/a = 1
10/a = 1 - 10/b
a = 10/(1 - 10/b) = 10b/(b-10)
Calculating time taken when they work together:
Let x be the number of days taken when A and B work together
A completes x/2 sets of work
B completes x/2 sets of work
x/2 * (2/a + 2/b) = 1
x/2 * (a+b)/ab = 1
x = 2ab/(a+b)
Substitute the values of a and b:
x = 2(10a/(a-10))(10b/(b-10)) / (10a/(a-10) + 10b/(b-10))
x = 36/7 days
Therefore, when A and B work together, they complete the task in 36/7 days. Option D is the correct answer.
A can complete the task in 'a' days
B can complete the task in 'b' days
Approach:
1. Let's first calculate the fraction of work done by A and B in a day.
2. Then, we will calculate the fraction of work done by A and B in 2 days.
3. Using this information, we will calculate the number of days taken when they work together.

Fraction of work done by A and B in 2 days:
In 2 days, A completes 2/a of the work
In 2 days, B completes 2/b of the work
Given conditions:
When A starts, they finish the task in exactly 10 days.
A works 2 days at a time, so in 10 days, A works 5 sets of 2 days.
Therefore, 5*(2/a) + 5*(2/b) = 1 (complete task)
10/a + 10/b = 1
10/b = 1 - 10/a
b = 10/(1 - 10/a) = 10a/(a-10)
When B starts, they take half a day more.
Similarly, 5*(2/b) + 5*(2/a) = 1
10/b + 10/a = 1
10/a = 1 - 10/b
a = 10/(1 - 10/b) = 10b/(b-10)
Calculating time taken when they work together:
Let x be the number of days taken when A and B work together
A completes x/2 sets of work
B completes x/2 sets of work
x/2 * (2/a + 2/b) = 1
x/2 * (a+b)/ab = 1
x = 2ab/(a+b)
Substitute the values of a and b:
x = 2(10a/(a-10))(10b/(b-10)) / (10a/(a-10) + 10b/(b-10))
x = 36/7 days
Therefore, when A and B work together, they complete the task in 36/7 days. Option D is the correct answer.

Let suppose that Adam's age is 'A', and Mike's age is 'M'. From the statement of the questions, we deduce following two equations.
A = 2+M and also A2= M2+28 -> A2 - M2 = 28 -> (A+M)(A-M)=28 and then putting
A-M=2, we get (A+M) = 14. Therefore, the sum of Adam's age and Mike's age is 14.

Understanding the Problem
We are given two negative integers, \( k \) and \( p \), that are not both even. This means at least one of them is odd.
Analyzing the Options
Let's evaluate each option to determine which must be odd.
Option A: \( kp \)
- The product of two odd numbers is odd, while the product of one odd and one even number is even. Since we don’t know the parity of \( k \) and \( p \) definitively, \( kp \) may be odd or even.
Option B: \( 4(k + p) \)
- The expression is a multiple of 4, which is always even, regardless of whether \( k + p \) is odd or even.
Option C: \( k - p \)
- This can be odd or even depending on the values of \( k \) and \( p \). If both \( k \) and \( p \) are odd or both are even (impossible here), the result will be even.
Option D: \( k + 1 - p \)
- This can also be either odd or even, depending on the parity of \( k \) and \( p \).
Option E: \( 2(k + p) - 1 \)
- Here, \( k + p \) must be odd (since one of \( k \) or \( p \) is odd). Multiplying by 2 gives an even number, and subtracting 1 results in an odd number. Therefore, \( 2(k + p) - 1 \) must be odd.
Conclusion
Thus, the only expression that must always be odd is:

Step 1: Analyze the Question
In this question, we are presented with a series of parts that make up the whole- in this case, the number of students in an art class. Notice that most of the whole is identified as fractions of the whole, while one part is identified as a specific quantity. We can use this to our advantage.
Step 2: State the Task
Determine the sum of the fractions in the question stem (sculptures, oil paintings, watercolors), since this makes up all but one part of the whole number of students. Subtracting this fraction from 1 will provide the fraction of the whole that is the remaining part (mosaics). Finally, we will solve for the number of students in the class. Note that this question can also be solved by Backsolving, since all of the answer choices are numbers and we can test out the answer choices to see if 10 pieces remain after calculating the number of other pieces of artwork.
Step 3: Approach Strategically
We are told that 1/3 of the students create sculptures, 1/8 create oil paintings, 1/2 create watercolors, and the remaining 10 pieces are mosaics. Let's assume that the total number of students in the class is x. Then the sum of the sculptures, oil paintings, and watercolors is as follows:
(1/3)x + (1/8)x + (1/2)x = x(1/3 + 1/8 + 1/2) = x(8/24 + 3/24 + 12/24) = x(23/24)
So the sum of the sculptures, oil paintings, and watercolors is 23/24 of the art in the exhibit. Therefore. the remaining 10 pieces must be 1-23/24 = 1/24 of the total pieces. We can set up the equation:
(1/24)x = 10; x= 240
Choice (C) is correct.
Step 4: Confirm Your Answer
Plug your value for x into the original equation to confirm your calculations are correct.

First, calculate the price of the laptop this year. Then, use that price to determine what the price will be next year. After a 15% decrease in price, the system would sell for 85% of $800: 0.85 x $800 = $680. If there is a 25% increase next year, the system would sell for 125% of this year's price. That would be 125% of $680: 1.25 x $680 = $850 (D).

Step 1: Analyze the Question
This question tests our ability to think critically about the characteristics of remainders in division We are told that some number, m, has a remainder of 2 when divided by 5.
This question tests our ability to think critically about the characteristics of remainders in division We are told that some number, m, has a remainder of 2 when divided by 5.
Step 2: State the Task
We can use our knowledge of number properties to take a particularly strategic approach to this problem. The key will be to pick simple, permissible numbers and apply them to the problem in the question stem.
We can use our knowledge of number properties to take a particularly strategic approach to this problem. The key will be to pick simple, permissible numbers and apply them to the problem in the question stem.
Step 3: Approach Strategically
Ask yourself what numbers would be permissible for m. Since m has a remainder of 2 when divided by 5, m could be any number 2 greater than a multiple of 5. The simplest number to substitute for m is 7. We know that 5 goes into 7 one time with a remainder of 2. Now, apply 7 to the rest of the question stem: 3 m divided by 5. Well, 3 x 7 = 21, and 21 divided by 5 would leave a remainder of 1. That's (B). Picking Numbers is the most efficient approach to this common GMAT question type.

Step 4: Confirm Your Answer
To double-check your work, you could test any other permissible number for m: 12, 17, 22, etc. If you tried 12, you would find that 3 x 12 = 36 and 36 divided by 5 leaves a remainder of 1. This confirms that (B) is the correct choice.

TRIPS objectives:
Reducing trade distortions and bottlenecks.
Promoting effective and adequate intellectual property rights (IPR) protection.
Ensuring that measures and procedures for enforcing intellectual property rights (IPR) do not become hurdles to legitimate commerce.
Provision on dispute settlement.

2 is for selecting 2 numbers out of 100.25 is divided because we are removing all the prime numbers between 1-100 I.e. 25.99 maybe because we are removing 1 from the list because 1 multipled with any number would result in the same number only and that’d have 2 factors, 1 and itself.I’m a bit unsure about 99 though, if someone can confirm, that’d be great.

Step 1: Analyze the Question
This question gives us a complicated-looking equation with one variable. The answer choices are just numbers.
Step 2: State the Task
Our task is to solve for the value of x.
Step 3: Approach Strategically
Since the answer choices are potential values for the variable in the equation, we could just plug those values back in to see which value makes the equation true. Backsolving is an option whenever you can manageably plug an answer choice into the question stem. Let's say that you started with (D), x = 3/2 That makes the equation:
That's not a true statement. So we need to try other values. It's very hard to see whether you needed a larger or smaller x, so it's perfectly fine to try different answer choices. (C) is a sensible choice to test next, as it's the most manageable. It would leave you with 2 + 2 = 3 - 3, which is also false. (E) is the next most manageable. Plugging 5 in for x makes the equation
Step 4: Confirm Your Answer
Reread the original equation, making sure you didn't make a careless error such as switching the plus and minus signs
