Question

If twice the son age is added to father age the sum is 70 But if twice the father age is added to son age,the sum is 95 .Find both ages.​

Answer 1

hope it will help you

Answer 2

let the age of the father be x and the age of the son be y

according to the conditions,

2y+x=70 ..............(1)

2x+y=95 ..............(2)

multiplying equation (1) into 2 we get 

subtracting equation (2) from equation (3)

4y+2x=140 .........(3)

 y+2x=  95

---------------

3y     = 45

y=15 ..................(4)

substituting (4) in (2) we get

15 +2x=95

2x=80

x=40.

Therefore the age of the father is 40yrs and that of the son is 15 yrs
