Question

The sum of present ages of Father & son is 55 years. The sum of Father's age and twice the age of son is 70. Find the present ages of Father and son?​

Answer 1

Answer:

let the father's age be = x

the sons age be = y

sum of their ages = 55

x + y = 55 -------------1

twice of the age of the son = 2y

sum of the age of the father and the twice of the age of the son = 70

x + 2y = 70-----------2

sub eq 1 and 2

x + y = 55

x + 2y = 70

symbol change then x and -x will be cancelled

then

-y = -15

y = 15

age of father = x = 55 - y = 55 - 15 = 40

therefore age of father = 40

age of son = 15

I think this is the answer............I hope this helps u
