Question

Mona father is thrice as old as Mona after 12 year his age will be twice that of her daughter find their present age​

Answer 1

let the age of Mona be x

hence the age of her father will be 3x

after 12 years,

age of Mona will be x+12

and the age of her father will be 3x+12

according to condition,

2(x+12)=3x+12

2x+24=3x+12

24-12=3x-2x

12=x

age of Mona is x=12

age of her father 3x=3*12=36
