Question:

A can do 1/11 of work in 1 hour and b can do the same work in 8 hours. If they work together, find the time taken by A and B to complete the whole work.

Answer:

A and B can complete the whole work in 4 hours 63 mins.

Step-by-step explanation:

A can do 1/11 of work in 1 hour

B can do whole work in 8 hour

So, In 1 hours b can do 1/8 of work

In 1 hour, A and B together can do ( 1/11 + 1/8 ) = 19/88 of work

So, A and B can complete the whole work in 88/19 = 4 hours 63 mins
