A and B together have Sterling 1210. If 4/15 of A's amount is equal to 2/5 of B's amount, how much amount does B have?


A. Sterling 460 B. Sterling 484
C. Sterling 550 D. Sterling 664
Answer: Option B
Explanation: 4/15A = 2/5B

A = (2/5 x 15/4)B

A = 3/2 B

A/B = 3/2

A : B = 3 : 2.

B's share = Sterling (1210 x 2/5) = Sterling 484.
