Robin can do a work alone in 9 days. Amit can do the same work alone in 6 days. Both of them finish the work together and they get a total Rs. 2500. What is the share (in Rs.) of Robin?
1). 1700
2). 1200
3). 1500
4). 1000
Robin’s 1 day work = 1/9
Amit’s 1 day work = 1/6
When they work together, they received Rs. 2500
? Ratio of wages = Ratio of work efficiencies
⇒ Robin’s share? Amit’s share = (1/9) ? (1/6) = 6 ? 9 = 2 ? 3
Sum of ratios = 2 + 3 = 5
∴ Robin’s share = 2/5 × 2500 = Rs. 1000
