Question

monu father is five times older than monu after 8 years his age will be three times monu age that time find their present ages

Answer 1

Let monu's age be x
Monu's father's age will be 5x
After 8 yrs....
Monu's age=x+8
Father's age=5x+8
According to the statement...after 8 years father's age will be 3 times monu's age
So.....
5x+8 =3(x+8)
5x+8 =3x+24
5x-3x=24-8
2x=16
X=8
Therefore monu's present age is x=8
And father's present age is 5x =5×x=5×8=40

Answer 2

Let monu's age be x
Monu's father's age will be 5x
After 8 yrs....
Monu's age=x+8
Father's age=5x+8
According to the statement...after 8 years father's age will be 3 times monu's age
So.....
5x+8 =3(x+8)
5x+8 =3x+24
5x-3x=24-8
2x=16
X=8
Therefore monu's present age is x=8
And father's present age is 5x =5×x=5×8=40
