Answer:
30 years
Explanation:
Shobo's age=x years
His mother's age= 6 times of Shobo's age= 6x years
Five years from now
Shobo's age= (x+5) years
According to the problem
x+5=1/3 of his mother's present age
x+5=6x/3
x+5=2x
5=2x-x
5=x
Therefore Shobo's present age is 5 years
His mother's age =6x
6x5=30 years
