Question
P started a business investing Rs.12000. After 3 months,
Q joined her with the capital of Rs.18000. After another 6 months, R joined them with the capital of Rs.24000. At the end of the year, they made a total profit of Rs.4200. Find the share of R.Solution
P invested her capital for 12 months, Q for 9 months and R for 3 months. So, ratio of their capitals = (12000 × 12):(18000 × 9):(24000 × 3) ⇒ 144000 : 162000 : 72000 ⇒ 8 : 9 : 4 Therefore, R’s share = 4200 x (4/21) = Rs.800
