P can do 1/4th of work in 10 days, Q can do 40% of work in 40 days and R can do 1/3rd of work in 13 days. |
So, Number of days in which P can do whole work = 10 × 4 = 40 days Number of days in which Q can do whole work = 40/0.4 = 100 days Number of days in which R can do whole work = 13 × 3 = 39 days Hence, R will complete the work first. |
