Answer 1

Answer:

14/3

Step-by-step explanation:

Given A completes a piece of work in 2 days, B in 4 days, C in 9 and D in 18 days. They form groups of two such that difference is maximum between them to complete the work. What is difference in the number of days they complete that work?

The difference will be maximum if A and B form a pair and C and D form a pair.

Now A and B together can complete the work in 2 x 4 / 2 + 4

Now C and D together can complete the work in 9 x 18 / 9 + 18

So the difference will be 6 – 4/3 = 14/3 days.
