Answer 1

Question

A man's age is three times the sum of ages of his two sons. After 5 years, age will be twice the sum of the ages of his sons. Find the age of man.

solution.

• Let the sum of ages of two sons be x years

• Age of man = 3xyears

• After 5 years age of the man =(3x+5)years

Sum of ages of two sons =(x+10)years

Given,

• (3x+5)=2(x+10)

• ⇒ (3x+5)=2x+20

• ⇒ x=15

Hence 3x=3(15)=45

∴ Present age of father is 45years.
