a) Rs. 2840
b) Rs. 4028
c) Rs. 4280
d) Rs. 4820
Answer: c
Explanation: Let C’s capital be Rs. x
A : B : C = 2560 : 2000 : x
$$\eqalign{
& {\text{A’s share}} \cr
& = {\text{Rs}}{\text{.}}\left( {1105 \times \frac{{2560}}{{4560 + x}}} \right) \cr
& \therefore 1105 \times \frac{{2560}}{{4560 + x}} = 320 \cr
& 320x + 1459200 = 2828800 \cr
& 320x = 1369600 \cr
& x = 4280 \cr} $$
