Question

Example 7. Suresh can finish a task in 24 days. Along with Monika, Suresh completed the task & they were paid Rs. 108 & Rs. 162 respectively. How many days they would have taken to finish the work together?​

Answer 1

No of days taken by Suresh to finish the work=42.

So part of work done by Suresh in one day =1/42.

Since Mahesh is 1/5 times more efficient as Suresh,part of work done by Mahesh in 1 day =1/42 + (1/5)×(1/42). = (1/42) + (1/210) =6/210=1/35.

So Mahesh can finish the work in 35 days.
