Question
P started a business investing Rs.15000. After 4 months,
Q joined her with the capital of Rs.20000. After another 6 months, R joined them with the capital of Rs.30000. At the end of the year, they made a total profit of Rs.6000. Find the share of R.Solution
P invested her capital for 12 months, Q for 8 months and R for 2 months. So, ratio of their capitals = (15000 × 12):(20000 × 8):(30000 × 2) ⇒  180000 : 160000 : 60000 ⇒  9 : 8 : 3 Therefore, R’s share = 6000 x (3/20) = Rs.900
