The ratio between the present ages of A and B is 5:3 respectively.
Question 1:
The ratio between the present ages of A and B is 5:3 respectively. The ratio between A's age 4 years ago and B's age 4 years hence is 1:1. What is the ratio between A's age 4 years hence and B's age 4 years ago?
A. 1:3
B.2:1
C.3:1
FeedbackLet the present ages of A and B be 5x and 3x years respectively. Then, (5x - 4)/(3x + 4) = 1/1 2x = 8 => x = 4 Required ratio = (5x + 4):(3x - 4) = 24:8 = 3:1
D.4:1
