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, then what is the share of Priya?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. Rs. 2000.
Share of A = (Efficiency of A/Total efficiency) × Total share
Total work (LCM of 10, 12 and 15) = 60
Efficiency of Rani = 60/10 = 6
Efficiency of Priya = 60/12 = 5
Efficiency of Guddu = 60/15 = 4
Total efficiency = 6 + 5 + 4 = 15
Hence, share of Priya = (5/15) × 6000 = Rs 2000
