Question
‘A’, ‘B’ and ‘C’ started a business by
investing Rs. 1500, Rs. 1800 and Rs. 1200, respectively. After 4 months, ‘B’ left and ‘A’ and ‘C’ added Rs. 600 each to their respective initial investment. Find the ratio of annual profit received by ‘A’, ‘B’ and ‘C’.Solution
Ratio of the annual profit received by ‘A’, ‘B’ and ‘C’ => {(1500 × 4) + (2100 × 8)}:(1800 × 4):{(1200 × 4) + (1800 × 8)} = 19:6:16
