7x5: 5xk = 7:10
k = 10 months

W = 10th from the left

R = 4th from the right = (30 - 4 + 1= ) 27th from left

 No of boys between R and W = (27 - 10) - 1 = 16

We know that Time is inversely proportional to Efficiency

Here given time ratio of P & P+Q as

P/P+Q = 150/100 = 3:2

Efficiency ratio of P & Q as

P:Q = 2:1 ....(1)

Given Efficiency ratio of Q & R as

Q:R = 3:1 ....(2)

From (1) & (2), we get

P:Q:R = 6:3:1

P alone can finish the work in

22.5(3+1)/6 = 15 days.
