Question

X and Y together can dig a trench in 14 days. X alone dig in 25 days. in how many days Y alone can dig it.​

Answer 1

Answer:

Work done by x and y in one day :

(1/14)th of total work

Work done by x in one day :

(1/25)th of total work

So let Work done by y in one day :

(1/h)th of total work

so 1/h +1/25 = 1/14

=> h = (350/11) days

So y takes approx. 31.8 days to complete the work.

Answer 2

Answer:

Step-by-step explanation:

work done in 1 day by both X and Y = 1/14

work done in 1 day by X = 1/25

work done by Y in one day = 1/14 - 1/25

                                              = 11/350

time taken by Y to dig the trench = 32 days
