Directions: Answer the questions based on the information given below.

A, B, and C distributed Rs. [P] among themselves in the ratio 5 : 6: 4 respectively. After spending 20% of their respective shares, A and C invested the remaining amount in scheme 'X' for 4 years and in scheme 'Y' for 2 years, respectively. Scheme 'X' offers 20% p.a. simple interest while scheme 'Y' offers 50% p.a. compound interest, compounded annually. The interest received by A is Rs. 3200 less that of C. B purchased a car from his share of money and sold it at 20% profit. If he had sold the car at [Q]% profit, then he would have received Rs. 1200 more. A and C invested the interest received by them from scheme 'X' and scheme 'Y', respectively, in a business together. After 6 months, B also joined them with the sum obtained by him on selling the car. If the profit received by B at the end year is Rs. 9000, then the total profit received by all three of them at the end of the year will be Rs. [R]. If A, B, and C were assigned to a job for Rs. 375, and A received Rs. 3Q out of it then the time taken by B to finish the same work is [S] days. Further, it is known that A and B together can complete the work in 15 days and A and C together can complete the same work in 12 days.
