A and B are two partners in a firm sharing the profit in the ratio 4 : 5. If the firm earns a profit of Rs. 14130, then profit to be received by B ?

$$\eqalign{ & {\text{A}}:{\text{B}} \cr & 4:{\text{ }}5 \cr & {\text{According to the question,}} \cr & \left( {4 + 5} \right){\text{units}} = {\text{Rs}}{\text{. 14130}} \cr & {\text{1 unit}} = \frac{{14130}}{9} = {\text{Rs}}{\text{. }}1570 \cr & 5{\text{ units}} = 5 \times 1570 = {\text{Rs}}{\text{. 7850}} \cr & \therefore {\text{Hence share of B}} = {\text{Rs}}{\text{. 7850}} \cr} $$
