Question

. Arnav is thrice as old as his sister. In 10 years from now , the sum of their ages will be 48 years. How old are they now

Answer 1

Answer:

Let the son's present age is x years, then the age of the father is 3x years.

from the given conditions,

After 12 years, father's age 2×(x+12)

also after 12 years, father's age is (3x+12)

Hence, 2(x+12)=(3x+12)

⇒2x−3x=12−24

⇒−x=−12

⇒x=12

At present, Father's age is 12×3=36.

Hence, son's present age is 12 and father's present age is 36.
