Rani can do a work alone in 10 days, Priya can do the same work alone in 12 days and Guddu can do the same work alone in 15 days. If they do that work together and they are paid Rs 6000, them what is the share of Priya?

Rs 2000

Total work = LCM of 10, 12, 15

Ratio of efficiencies of Rani, Priya and Guddu = 6 : 5 : 4

Wages ∝ Efficiency 

Share of Priya = $\frac{5}{15}$ x Rs 6000

                     = Rs 2000
