A, B and C entered in to a partnership by investing Rs. 15400, Rs.18200 and Rs. 12600 respectively. B left after 6 months. If after 8 months, there was a profit of Rs. 28790, then what is the share of C in the profit ?

Solution (By Examveda Team)

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