Answer 1

Answer:

13.75 day

Step-by-step explanation:

x can do the work in = 25 days

he can do in 1 day = 1/25

y can do the work in = 20 days

he can do in one day = 1/20

work done by together in 1 day = 1/25+1/20

= 4+5/100 = 9/100

work done by together in 5 day = 9/100×5=9/20

after 5 days remaining work = 1-9/20= 11/20

therefore x can do the remaining work in

11/20÷1/25= 55/4

= 13and 3/4 days ie 13.75 days
