Step-by-step explanation:

When P, Q and R work together, one-day work = 1/20 + 1/15 + 1/25 = 47/300

Total time taken by P, Q and R to complete the work = 300/47 days

Total work done by Q in (300/47) days = (300/47) × 1/15 = 20/47

Money earned by Q = Total money × Work done by Q

Share of Q = 9600 × 20/47 ≈ Rs. 4085
