Question

Raju’s father is thrice as old as Raju. After 12 years, his age will be twice that of his son. Find their present ages.

Answer 1

Answer:

Raju's age = 12 year

Raju's father age = 24 year

Step-by-step explanation:

Let the present age of Raju is x.

Then his father's present age is 3x.

After 12 years there age will be 3x+12 and x+12

And his father will twice of his son.

Then, 3x+12/x+12 = 2/1

or 2×(x+12) = 1×(3x+12)

or 2x+24 = 3x+12

or 2x-3x = 12-24

or -1x = -12

or x = -12/-1 = 12

Hence, present age of Raju and his father is 12 year and 12×2 = 24 year.

$\frac{x}{y} = \frac{a}{b} \\ or \: \: x \times b = y \times a$
