P and Q were assigned to do a work for an amount of 1200. P alone can do it in 15 days while Q can do it in 12 days. With the help of R they finish the work in 6 days. Find the share of R ?

Correct Answer: 120

Explanation:

1/15 + 1/12 + 1/R = 1/6, we got R = 60 (it means R will take 60 days to complete the work alone)



so ratio of work done by P:Q:R = 1/15 : 1/12 : 1/60 = 5 : 4 : 1



so R share = (1/10) x 1200 = 120.
