Question

The sum of present age of a father and son is 60 years six years ago father's age was five times the age of 15

Answer 1

let father age be x

let son age be y

by condition 1

1. x+y=60
2. x-6=5(y-6)

• x=60-y

substitute in eq2

60-y-6=5y-30

60-6+30=5y+y

84=6y

y=16

substitute

x+16=60

x=44

the father age is 44years and son age is 16years
