One year ago, the ratio of the age (in years) of A to that of B was 4
Right Answer is: B
Let the age of A and B before one year are 4x and 3x respectively.
A. T. Q.
(4x+3+1)/(3x+3+1) = 6/5
20x + 20 = 18x + 24
2x = 4
x = 2
Present age of A = 4x + 1 = 9 years
Present age of B = 3x + 1 = 7 years
Required age ratio after 9 years –
A/B = (9+9)/(7+9) = 18/16
A/B = 9/8
