Question

Reenu’s father is thrice as old as Reenu. After 12 years he will be just twice his daughter’s age. Find their present ages.

Answer 1

Answer:

Let us assume that the present age of Renu be x years, then the present age of her father will be 3X years.

The equation we get:

2(X + 12) = 3X + 12

2X + 24 = 3X + 12

2X - 3X = 12 - 24

-X = -12

X = 12 years.

Since Renu's present age is 12 years, then her father's present age will be 3 x 12 = 36 years.

Ans: 36 years and 12 years.
