Answer 1

Answer:

Father's age: 40years

son's age: 15 years

Step-by-step explanation:

Let father's present age be x and son's present age be y.

Given:

x +2y=70

x=70-2y

Also given,

2x+y=90.

Therefore,

2(70-2y)+y=95

140-4y+y=95

-3y= 95-140 = -45

y= -45/-3

y=15 years.

x=70-2y

x=70-2 x 15

x=70-30

x=40 years.

Hence,

Father's age: 40years.

Son's age: 15 years.
