• 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
