Question

The present age of Sahil's mother is 3 times the present age of Sahil. After 5 years their ages will added to 66 years find the present age of Sahil.

Answer 1

Let the present age of Sahil be 'x'.
Then, present age of Sahil's mother is '3x'

After 5 years, age of Sahil = x+5
Age of Sahil's mother = 3x+5

Sum of their ages after 5 years = 66

Therefore,
(x+5)+(3x+5)=66
4x+10=66
4x=66-10
4x=56
x=56/4
x=14

Therefore, present age of Sahil is 14 years

Answer 2

let the present age of sahil be =x
then the age of sahil mother =3x
after five years sahil age =x+5
after five is sahils mother age =3x+5
sum of their age after five years= 66
therefore

[x+5] +[3x+5]=66
4x +10=66
4x =66-10
4x =56
x=56/4
x =14
the present age of sahil is 19
