Question

how to solve this question?​

Answer 1

Answer:

No of days taken by X to finish the work= 40

So part of work done by X in 1 day= 1/40

Part of work done by X in 8 days= 8/40 = 1/5

The remaining part = 1 - 1/5 = 4/5

No of days taken by Y to finish 4/5 part = 16

Part of work done by Y in 1 day = (4/5)/16

=(4/5)(1/16)= 1/20

Part of work done by both together in 1 day = (1/40)+(1/20)= 3/40

So number of days taken both together to finish the work = 1 / (3/40) 40/3 = 16 2/3 days.
