Rs. 2220, then the share of A exceeds that of B by
(a)
Rs. 120
(b)
FS 190​

Answer 1

Step-by-step explanation:

Ratio of shares of A, B and C = 1/20 : 1/25 : 1/30 = 15 : 12 : 10

∴ A's share = Rs.(2220 x 15/37) = Rs. 900

B's share = Rs.(2220 x 12/37) =Rs. 720

Thus, the share of A exceeds that of B by Rs.(900 - 720) = Rs. 180.
