Answer 1

Step-by-step explanation:

Answer:75 days

Step-by-step explanation:

A has completed 5x100/25= 20% work in 5 days and remaining work is 100%-20% = 80%

A's work in 5 days = 20%

So in 15 days = 15x20/5 -60% So work done by B in 15 days -80%-60%= 20%

When B completes 20% in 15 days Then 100% = 15x100/20 = 75 days
