Question

A mother is twice as old as her daughter. Six years ago their joint ages was 54 years. How old is the mother now?

Answer 1

let the mother's age be x years and

daughter's age be y years

A.T.P.

x=2y

after 6 years

x+6+y+6=54

x+y+12=54

put x=2y in above equation

2y+y+12=54

3y=54-12=42

y=42/3

y=14

x=2y

x=2×14=28

•°•mother's age=28 years

daughter's age =14 years
