Abhay Sen answered |
► Total number of blocks = 8
► Number of shaded blocks = 1
► Number of unshaded blocks = 7
► Number of shaded blocks = 1
► Number of unshaded blocks = 7
⇒ Fraction of Shaded area = No. of shaded blocks/ Total number of blocks = 1/8.
Thus, the correct answer is Option B.

Kavya Rane answered |
In a fraction a/b, a is called the numerator and b is called the denominator. A fraction is a way to represent parts of a whole. The denominator b represents the number of equal parts the whole has been divided into, and the numerator a represents how many parts are included.
A fraction in which numerator is less than denominator is called proper fraction, means a fraction that is less than 1.
example: 1/2, 1/4, 3/8 etc.

Tarun Sharma answered |
Explanation:
When two proper fractions are multiplied, the result is always less than each of the fractions that are multiplied. This can be explained using the following points:
1. Proper fractions are those fractions whose numerator is less than the denominator.
2. When two proper fractions are multiplied, the resulting fraction has a numerator which is the product of the numerators of the two fractions and the denominator is the product of the denominators of the two fractions.
3. Since the numerator and denominator of each fraction are positive integers, the product of the numerators and the product of the denominators are both positive integers.
4. When we compare the product of the two fractions with each of the fractions that are multiplied, we can see that the product is always less than each of the fractions.
5. This is because the numerator of the product is the product of the numerators of the two fractions, which is always less than each of the numerators, and the denominator of the product is the product of the denominators of the two fractions, which is always greater than each of the denominators.
6. Therefore, the product of two proper fractions is always less than each of the fractions that are multiplied.
Conclusion:
Hence, option 'C' is the correct answer as the product of two proper fractions is always less than each of the fractions that are multiplied.

Mahesh Sen answered |
Let's denote:
- Total number of pages in the book as x
Understanding the problem:
- Guru reads 3/5 of the book.
- Remaining pages = 80
Setting up the equation:
- If Guru reads 3/5 of the book, then he has 2/5 of the book left to read.
- We know that 2/5 of the book is equal to 80 pages.
So, we can write the equation:
- (2/5) * x = 80
Solving the equation:
To find x, we can multiply both sides of the equation by 5/2:
- x = 80 * (5/2)
- x = 40 * 5
- x = 200
Therefore, the total number of pages in the book is 200.

Vandana Mukherjee answered |
- Given that 2494 ÷ 14.5 = 172
- To find 24.94 ÷ 1.45, we need to move the decimal point one place to the right for both numbers
- This gives us 249.4 ÷ 14.5
- Dividing 249.4 by 14.5 gives us 17.2
- Therefore, the answer is 17.2
- To find 24.94 ÷ 1.45, we need to move the decimal point one place to the right for both numbers
- This gives us 249.4 ÷ 14.5
- Dividing 249.4 by 14.5 gives us 17.2

Avi Khanna answered |
Given numbers are :
0.3 , 3 , 0.03 and 0.002
We know that Average = Sum of numbers divided by total numbers
Average = 0.3 + 3 + 0.03 + 0.002 / 4
= 3.332 / 4
= 0.833
So, Average = 0.833
Therefore, option A is the correct answer.

Mehul Sen answered |
Given numbers are :
3.003 and 2.05
Now, Sum of numbers = 3.003 + 2.05
= 5.053
Difference of numbers = 3.003 - 2.05
= 0.953
Adding the Difference of numbers to th Sum of numbers , we get
5.053 + 0.953 = 6.006
So option A is the correct answer.

Deepali desai answered |
To find the equivalent fraction of 8/11 with a numerator of 40, we need to multiply both the numerator and the denominator by the same number to maintain the ratio between them.
Let's call the number we multiply by "x".
When we multiply the numerator (8) by "x", we get 8x.
When we multiply the denominator (11) by "x", we get 11x.
Since we want the new numerator to be 40, we set up the equation:
8x = 40
To solve for x, we divide both sides of the equation by 8:
x = 40/8
Simplifying further, we get:
x = 5
Now that we know x = 5, we can find the new equivalent fraction by multiplying both the numerator and the denominator of the original fraction (8/11) by 5:
(8 * 5) / (11 * 5)
Which simplifies to:
40/55
Therefore, the equivalent fraction of 8/11 with a numerator of 40 is 40/55.
So, the correct answer is option C.
Let's call the number we multiply by "x".

Now that we know x = 5, we can find the new equivalent fraction by multiplying both the numerator and the denominator of the original fraction (8/11) by 5:
(8 * 5) / (11 * 5)
Which simplifies to:
40/55
Therefore, the equivalent fraction of 8/11 with a numerator of 40 is 40/55.
So, the correct answer is option C.

Anita Menon answered |
Suppose commodity X will cost 40 paise more than Y after Z years. Then,
► (4.20 + 0.40Z) - (6.30 + 0.15Z) = 0.40
► 0.25Z = 0.40 + 2.10
► Z = (2.50 / 0.25) = 10
► 0.25Z = 0.40 + 2.10
► Z = (2.50 / 0.25) = 10
∴ X will cost 40 paise more than Y 10 years after 2001 i.e in 2011.

Mehul Sen answered |
First, we convert each fraction into a like fraction.
2/9 = (2 x 7)/(9 x 7) = 14/63
2/3 = (2 x 21)/(3 x 21) = 42/63
8/21 = (8 x 2)/(21 x 3) = 24/63.
If denominators are the same, then, greater the numerator, the greater will be the fraction.
∵ 42 > 24 > 14
⇒ (2/3) > (8/21) > (2/9)
Thus, the correct answer is Option A.
2/9 = (2 x 7)/(9 x 7) = 14/63
2/3 = (2 x 21)/(3 x 21) = 42/63
8/21 = (8 x 2)/(21 x 3) = 24/63.
If denominators are the same, then, greater the numerator, the greater will be the fraction.
∵ 42 > 24 > 14
⇒ (2/3) > (8/21) > (2/9)
Thus, the correct answer is Option A.

Siddharth Sharma answered |
Let the number of matches lost hex. The number of matches won = x+4.
Total matches played = x+x+4
We have, x+4 = 3/5 (2x+4) ⇒ x = 8
∴ Total matches played = 20
Total matches played = x+x+4
We have, x+4 = 3/5 (2x+4) ⇒ x = 8
∴ Total matches played = 20
