- A and B can finish a piece of work in 16 days and 12 days respectively. A started the work
and worked at it for 2 days. He was then joined by B. Find the total time taken to finish the
work
​

Answer 1

Answer:Average work=48(LCM of 16 and 12)

A does 48 work in 16 days

In 1 day 48/16=3work

B does 48 work in 12 days

In 1 day 48/12=4work

A done work for 2 days

So,work done by A 8n 2 days=2×3=6

Remaining work is 42

A+B together can do 7 work in a day

Thus,42/7=6days

Total days 6+2=8days
