Let the present age of B be x
Present age of A = x + 5
According to question,
( x + 5 - 5) / (x - 5) = 3 /2
=> ( x ) / (x - 5) = 3 /2
=> 2x = 3x - 15
=> 3x - 2x = 15
=> x = 15
Present age of B = 15 years
Present age of A = 20 years
Present age of A = x + 5
According to question,
( x + 5 - 5) / (x - 5) = 3 /2
=> ( x ) / (x - 5) = 3 /2
=> 2x = 3x - 15
=> 3x - 2x = 15
=> x = 15
Present age of B = 15 years
Present age of A = 20 years
