Answer 1

Hello friend ur answer is b

16 days

Work done by X in 4 days =1x 4=1.205

Remaining work =1 -1=4.55

(X + Y)'s 1 day's work =1+1=8=2.20126015

Now,2work is done by X and Y in 1 day.15

So,4work will be done by X and Y in15x4= 6 days.525

Hence, total time taken = (6 + 4) days = 10 days.
