Question

22. A can finish a piece of work in 20
days while B can finish it in 25
days. They began together and
worked for 5 days and then B fell
ill. In how many days A alone can
finish the remaining work?​

Answer 1

Answer:

11 Days

Step-by-step explanation:

A's one day work = 1/20 of the work

B's one day work = 1/25 of the work

A's 5 day work = 5/20 = 1/4

B's 5 day work = 5/25 = 1/5

Both 5 day work = 1/4 + 1/5 = 9/20

Full work = 20/20

Work left for A = 20/20 - 9/20 = 11/20

Therefor, A can finish the remaining work in 11 Days
