Question

After 10 years , Seema will be one and a half times as old as she is now,determine her present age.

Answer 1

Take the age of seema as X
So after 10 years it is (X+10)
Now she'll be 3/2 times the present age after 10 years
Therefore,
(X+10)= 3/2X
10=1/2X
X=20

Answer 2

let her present age be x
then the age after 10 years will be x+10
after 10 her will be 3/2 times her present age
so,
x+10=x×3/2
x+10=3x/2
2x+20=3x
x=20
so the present age of seema is 20 years
