a) Rs. 8712
b) Rs. 9432
c) Rs. 8352
d) Rs. 8568
Answer: a
Explanation:
$$\eqalign{
& {\text{Investment of A for 8 months}} = {\text{Rs}}{\text{.15400}} \cr
& {\text{Investment of B for 6 months}} = {\text{Rs}}{\text{.18200}} \cr
& {\text{Investment of C for 8 months}} = {\text{Rs}}{\text{.12600}} \cr
& {\text{Ratio of the share of A, B and C}} \cr
& = 15400 \times 8:18200 \times 6:12600 \times 8 \cr
& = 154 \times 8:182 \times 6:126 \times 8 \cr
& = 44:39:36 \cr
& {\text{Sum of the terms of ratio}} \cr
& = 44 + 39 + 36 \cr
& = 119 \cr
& {\text{ Share of C}} \cr
& = {\text{Rs}}{\text{.}}\left( {\frac{{36}}{{119}} \times 28790} \right) \cr
& = {\text{Rs}}{\text{.8710}} \approx {\text{Rs}}{\text{.8712}} \cr} $$
