Question

A man's age is 3 times the sum of the ages of his two sons, after 5 years, his age will be twice the sum of the ages of his two sons. find the age of the man.

Answer 1

Answer:

Let 2 sons age be x and y

Mans age is 3x +3y

After 5 years

x +y +10 = 2(3x+3y)

x+y+10 =6x +6y

x+y-6x-6y =10

5x+5y=10

x+y =2

Mans age = 6(2)

=12
