Answer 1

Answer:

1 day work of x = 1/25

1 day work of y = 1/20

1 day work.of x + y = 1/25 + 1/20

= 9/100

1 day work is 9/100

then 5 day work will be 5 * 9/100

9/20

Now remaining work = 1 - 9/20

= 11/20

1 day work of x = 1/25

Days in which x will complete the remaining work = 11/20 ÷ 1/25

= 11/5

Therefore, x will complete the remaining work in 5/11 days.
