Answer 2

Answer:

let represent the age of sanjay and his father x and y

today sanjay is 20 years younger than his father

therefore,

x=y-20

x-y=-20

10 years ago he was one -half as old as his father

x - 10 = ( y- 10) /2

2x-y=10

we get

x=30

y=50

age of father 10 years hence will be 50+10=60
