EXPLANATION.
Age of A is five more than that of B
=> Let the age of A = ( x + 5 ) years.
=> Let the age of B = x years.
5 years ago,
Present age of A = ( x + 5 ) - 5 = x years.
Present age of B = ( x - 5 ) years.
The ratio of was = 3:2.
=> x / x - 5 = 3/2
=> 2x = 3 ( x - 5 )
=> 2x = 3x - 15
=> x = 15 years.
Therefore,
Present age of A = ( x + 5 ) = ( 15 + 5 ) = 20 years.
present age of B = x = 15 years.
