Question

Raju can do a piece of work in 3 hours. Navin can do it in 6 hours. How long will they take if both work together?

Answer 1

Answer:

Step-by-step explanation:

Raju's one hour work = 1/3 ( he can complete 1/3 of total work in hour. so he can complete total work in 3hrs.)

Navin's 1 hour work = 1/6

Work done by them in hour together = 1/3 + 1/6 = 3/6 = 1/2.

They can together complete 1/2 of the work in one hour. So they can complete the work in 2hrs together.
