Question

the sum of fathers age and twist the age of his son is a 70 if we double the age of the father and add it to the age of his son the sum is 95 find their present ages

Answer 1

Answer,

Suppose father’s age(in years) be x and that son’s age be y.

Then,

x + 2y = 70…(I)
2x + y = 95 …(II)

Multiply Eq. I by 2 and equate,

2x + 4y = 140

-2x - y = -95 / 3y = 45

y = 45 / 3

y = 15

Substituting y = 15 in eq. (ll)

2x + 15 = 95
2x = 95 - 15
2x = 80
x = 80/2
x = 40

Son's age is 15 years.
Father's age is 40 years.
