Question

Rohit father is thrice as old as Rohit after 12 years he will be just twice his son find their present ages​

Answer 1

Answer :-

The present age of Rohit and Rohit's father are 12 years and 36 years respectively.

Solution :-

Let the present age of Rohit be 'x' years

Present age of Rohit's father = thrice the present age of Rohit = 3 * x = 3x

After 12 years

• Rohit's age = (x + 12) years

• Father's age = (3x + 12) years

Given

Age of Rohit't father after 12 years = twice his son's age after 12 years

⇒ 3x + 12 = 2(x + 12)

⇒ 3x + 12 = 2x + 24

⇒ 3x - 2x = 24 - 12

⇒ x = 12

Present age of Rohit = x = 12 years

Present age of Rohit's father = 3x = 3(12) = 36 years

Therefore the present age of Rohit and Rohit's father are 12 years and 36 years respectively.
