a) Rs. 1950
b) Rs. 1981.25
c) Rs. 2000
d) Rs. 2007.75

Answer: c
Explanation: Let the share of A = Rs. x
$$\eqalign{ & {\text{A}}:{\text{B}}:{\text{C}} \cr & {\text{Capital}} \to x:2x:\left( {4x – 50} \right) \cr & \left( {x + 2x + 4x – 50} \right) = 13950 \cr & 7x – 50 = 13950 \cr & 7x = 14000 \cr & x = 2000 \cr & {\text{Share of A}} = {\text{Rs}}{\text{. 2000}} \cr} $$
