A 's age is 6 times B's age .15 years hence, A will be three times as old as B then age of B is

Answer»

Let the age of B = x years.
Then, Age of A = 6x.

After 15 years,
Age of B= x+15
Age of A = 6x+15

According to QUESTION:-
6x+15 = 3(x+15)
6x + 15 = 3x +45
6x-3x = 45-15
3x = 30
x = 30/3
x = 10

So age of B = x = 10 years.
