2) Gaurav’s age after 15 years will be 5 times his age 5 years back. What is the present age of Gaurav?

1. 10 years
2. 18 years
3. 20 years
4. Cannot be determined
5. None of these

Answer: 1

Solution: Let Gaurav’s present age be x years. Then, Gaurav’s age after 15 years = (x + 15) years. Gaurav’s age 5 years back = (x – 5) years. Therefore x + 15 = 5 (x – 5) x + 15 = 5x – 25 4x = 40 x = 10. Hence, Gaurav’s present age = 10 years.

4) A is as much younger than B. B as he is older than C. If the sum of the ages is 50 years. What is the difference between the ages of B and A’s?

1. 1 year
2. 2 years
3. 25 years
4. Data inadequate
5. None of these

Answer: 4

Solution: Given that:
1. The difference of age b/w B and A = The difference of age b/w A and C.
2. Sum of age of B and C is 50 i.e. (B + C) = 50.
Question: B – A = ?.

Explanation:

B – A = A – C
(B + C) = 2A
Now given that, (B + C) = 50
So, 50 = 2A and therefore A = 25.
Question is (B – A) = ?

Here we know the value(age) of A (25), but we don’t know the age of B.
Therefore, (B-A) cannot be determined.
