Shobos mother present age is six times shobos present age. shobos age five years from now will be one third of his mother present age . what are their present ages

30 years

Step-by-step 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

4 and 5)16.97 or 12√2

6)15.59 or 9√3

7)y = 15.59 or 9√3     x =27

8)17.80
