A man buys an article for 20% less than its value and sells it for 20 % more than its value. What is his gain in percentage?
Let's assume actual value of article is Rs. 100.
Therefore, buying price is 100-20 = Rs. 80 (As man bought with 20% less than actual value). Selling price of article is 100 + 20 = Rs. 120 (As man sold with 20% more than actual value). Therefore, gain in percentage = [(120-80)/80] * 100 (40/80) * 100 = 50 %
Hence, option (a) is correct
Let the original price of the article be 'x'.
Buying price will be (80/100)x = 0.8x.
Selling price will be (120/100)x = 1.2x Therefore, gain in percentage =(profit/buying price) * 100 [(1.2x-0.8x)/0.8 x]* 100 0.5x * 100 = 50 %

The H.C.F of two numbers, each having three digits, is 19 and their L.C.M. is 3553. The sum of the numbers will be:
Let two numbers be 19x and 19y respectively, as 19 is the HCF of these numbers.
Now, LCM of 19x and 19y is 19xy and, according to the question LCM of these two numbers, =3553
Now we have two possible scenarios,
Either, x=17 and y=11 ---- (1)
Or, x=11 and y=17 ---- (2)
In the first scenario, where x=17 and y=11, numbers will be,
19x=19 × 17=323
19y=19 × 11=209.
Or, in the second case where x=11 and y=17, numbers will be 209 and 323.
Required sum would be =209+323 =532.
What is the remainder when 55 is divided by 8?
We know that 55= 5 × 52 × 52
The number immediately before 25 that is divisible by 8 is 24.
Hence, replace 25 with 24+1.
Then we have:
= 55 = 5(252) = 5(24 + 1)2 = 5(242 + 2 × 24 × 1 + 12)
= 5 × 242 + 5 × 2 × 24 + 5 × 1
Hence, the remainder is 5.

Present ages of Rajeev and Anand are in the ratio of 7: 10 respectively. Five years hence, the ratio of their ages will become 8: 11 respectively. If the Sum of the present age of Rajeev and Anand is ab. then, find what the unit digit of (ab) is?
Let the present ages of Rajeev and Anand be 7x and 10x years respectively.
⇒ 77x + 55 = 80x + 40
⇒ 3x = 15
⇒ x = 5
So, the present ages of Rajeev and Anand are (7 x 5)and (10 x 5) respectively.
The sum of their ages = (35 + 50) = 85 Hence, a = 8 and b = 5
Then, ab = 85
We know unit digit of 8 repeated after 4 powers. So, unit digit of 85 = unit digit of 81 ⇒ 8
A Salesman charges sales tax of x% upto Rs. 4,000 and above it he charges y%.

x = 5 and y =10
A father is six times as old as his son and the mother is five times as old as the son. Let the age of son be "x" then the sum of the father's and the mother's age is [(x - 1)2 - 1] years. What is the age of the son?
Given, the age of son is “x”
So, the age of father’s and mother’s be 6x and 5x respectively.
So, according to the question,
= 5x + 6x = [(x - 1)2 - 1]
⇒ 11x = x2 + 1 - 2x - 1
⇒ x2 = 13x
⇒ x = 13
So, the age of the son is 13 years

Correct the given equations by interchanging the two signs (10 - 14 ÷ 7 x 3 + 4 = 20)
Interchange of sign + and x makes the equation into 10 – 14 ÷ 7 + 3 x 4 = 10 - 2 + 3 × 4 = 20. Hence, option (b) is the correct answer.
a, b, c, d and e are five consecutive integers in increasing order of size. Which one of the following expressions is not odd?
Choice (A): ab+c
At least one of every two consecutive positive integers a and b must be even.
Hence, the product ab is an even number.
Now, if c is odd (which happens when a is odd), ab+c must be odd.
For example, If a=3, b=4, and c=5, then ab+c must equal 12 + 5 = 17, an odd number. Reject.
Choice (B): ab+d
We know that ab being the product of two consecutive numbers must be even. Hence, if d happens to be an odd number (it happens when b is odd), then the sum ab+d is also odd.
For example, If a=4, then b=5, c=6 and d=7, then ab+d =3×5+7=15+7=23, an odd number. Reject.
Choice (C): ac+d
Suppose a is odd. Then c must also be odd, being a number 2 more than a.
Hence, ac is the product of two odd numbers and must therefore be odd.
Now, d is the integer following c and must be even.
Hence, ac+d= odd + even = odd.
If a=3, then b=3+1=4, c=4+1=5 (odd) and d=5+1=6 (even) and ac+d =3 × 5 + 6 = 21, an odd number. Reject.
Choice (D): ac+e
Suppose a is an odd number.
Then both c and e must also be odd.
Now, ac is product of two odd numbers and therefore must be odd.
Summing this with another odd number e yields an even number.
For example, if a=1, then c must equal 3, and e must equal 5 and ac+e must equal 1 × 3 + 5 = 8, an even number.
Now, suppose a is an even number.
Then both c and e must also be even.
Hence, ac+e = (product of two even numbers) + (an even number) =(even number) + (even number) =an even number
If a=2, then c must equal 4, and e must equal 6 and the expression ac+e equals 14, an even number. Hence, in any case, ac + e is even. Correct.
Select the correct set of symbols which will fit in the given equation 5 0 6 8 = 48
These questions are mainly solved with a hit and trial method. Let check option (c), we get 5 × 0 + 6 × 8 = 48, Which is correct. So, (C) must be the right choice.
One year ago, the ratio between Rajeev’s salary and Shivani’s salary is 4:5. The ratio between their individual salary of the last year and current year is 2:5 and 10:11 respectively. If the total current salary of Rajeev and Shivani is 6200. Then find the current salary of Shivani?
Let previous year salary of Rajeev be 4x and Shivani be 5x Rajeev’s Previous year salary be 2y and Current year salary be 5y So, 4x is equal to 2y then 5y is equal to 10x.
Similarly, Shivani’s previous year salary was 10y and Current year salary was 11y. So, 5x is equal to 10y then 11y is equal to (11/2) x.
So, the current year salary ratio is 20: 11.
Given, 31x = 6200
⇒ x = 200 The current salary of Shivani = (11/31) × 6200 = 2200

The ratio of Adam’s age 4 years ago and Eve’s age after 4 years is 1: 1. Presently, the ratio of their ages is 4 : 3. Find the ratio between Adam’s age 4 years hence and Eve’s age 4 years
Currently, the ratio of their ages is 4: 3. Suppose, their ages are: 4x and 3x.
Adam’s age 4 years ago = 4x – 4
Eve’s age after 4 years = 3x + 4
The ratio of Adam’s age 4 years ago and Eve's age after 4 years is 1: 1
Solving, we get x = 8
We are required to find the ratio between Adam’s age 4 years hence and Eve’s age 4 years ago.
Adam's age: (4x + 4)
Eve's age: (3x – 4)
Putting the value of x, we get:
= = =
So, the required ratio is 9: 5
In a college, 12% of total students are interested in chess. 3/4 of the total students are interested in hockey. 10 % of the remaining students are interested in singing and the remaining 117 are interested in dancing. How many students are there in college?
Total percentage of students = 100%
Students interested in chess = 12%
Students interested in Hockey = 3/4 × 100 = 75%
Students interested in singing = 10% 13%
% of students interested in Dancing =[100 − (12 + 75 + 1.3)]% = 11.7%
So 11.7% = 117, then 100% =117/11.7 x 100 = 1,000
So, total number of students = 1,000
