Abdul is thrice as good a workman as Rehman and takes 10 days less to do a piece of work than Rehman takes. What is the number of days taken by Rehman to finish the work?
capacity of Abdul is thrice the capacity of Rehman. So, if Abdul finishes the work in x days then Rehman will take 3*x days.
so will will have, x+10=3*x 2*x=10 x=10/2 x=5.
so Abdul will take 5 days and
Rehman will take 3*5=15 days.
.Let N be the time takes Rehman to do the job . Abdul is tree times faster, then He will take N/3 . Since Abdul finishes 10 days before, we can write the following equation: N / 3 = N - 10 , N = 15 days The solution is 15 days
