QUESTION: 1

### Ashu's mother was three times as old as Ashu 5 yrs ago. After 5 yrs, she will be twice as old as Ashu. How old is Ashu today?

Solution:

Let the present age of Ashu's mother and Ashu be x and y respectively.
(x - 5) = 3 (y - 5)
⇒ x - 5 = 3y - 15
⇒ x - 3y = - 10 .....(i)

After 5 years:
(x + 5) = 2 (y + 5)
⇒ x + 5 = 2y + 10
⇒ x - 2y = 5 .....(ii)

From (i) and (ii) we get x = 35 and y = 15 yrs

Hence, option B is correct.
