Rani can do a work in 10 days, Priya can do the same work in 15 days and Guddu can do the same work in 12 days. If they do that work together and they are paid Rs. 9000, then what is the share of Priya?
Answer & explanation
Correct answer: option 1
Rani = 10 days, Priya = 15 days, Guddu = 12 days,
⇒ They are paid Rs. 9000 to work together = (6 + 4 + 5)x = 9000
⇒ x = \(\frac{9000}{15}\)
⇒ x = Rs. 600
⇒ Therefore, Share of Priya = 4 x 600 = Rs. 2400. ..(Efficinecy x Rate = Share)
