Answer 1

Answer:

hi

your answer is here !

Step-by-step explanation:

A and B’s one day’s work = 1/36.

B and C’s one day’s work = 1/48.

C and A’s one day’s work = 1/72.

If we add all this it will give us the work of 2A, 2B and 2C in 1 day i.e. (1/36) + (1/48) + (1/72) + (1/16)

That also implies that A, B and C’s one day’s work will be half of this i.e. (1/2) x (1/16) = (1/32)

From here it can found that they will complete the work in 32 days.
