1.	C is twice efficient as a and b is thrice time consume thanc.of a complete alone work in 12 days then find how many days all complete the work.
Answer» C is twice EFFICIENT as A efficiency is inversely proportional to time A takes 12 days to complete so C will TAKE 6 days And B takes thrice the time of C So B takes 18 days Now total work = LCM of 12, 6, 18 = 36 1 day work = 1/12 + 1/6 + 1/18 = (3+6+2) / 36 = 11/36 so whole work will be completed in 36/11 days = 3 3/11 days

C is twice efficient as a and b is thrice time consume thanc.of a complete alone work in 12 days then find how many days all complete the work.

Answer»

C is twice EFFICIENT as A

efficiency is inversely proportional to time

A takes 12 days to complete so C will TAKE 6 days

And B takes thrice the time of C

So B takes 18 days

Now total work = LCM of 12, 6, 18 = 36

1 day work = 1/12 + 1/6 + 1/18 = (3+6+2) / 36 = 11/36

so whole work will be completed in 36/11 days = 3 3/11 days
