Question

The present age of mohan's is three times the age of his son.After 8 years, the sum of their ages will be 72 years find their present ages

Answer 1

Answer:

Mohan's age is 42 years and his son's age is 14 years.

Step-by-step explanation:

Let Mohan's age be 'x' years and his son's age be 'y' years.

Then, x = 3*y  ...(i)

After 8 years, Mohan's age = x + 8

      and his son's age = y + 8

According to the question, after 8 years,

(x + 8) + (y + 8) = 72

x + y + 16 = 72

x + y = 56  ...(ii)

Using x = 3*y in (ii)

3y + y = 56

4y = 56

y = 14

using y = 14 in (i),

x = 3 * 14

x = 42.

∴ Mohan's age is 42 years and his son's age is 14 years.
