Answer 2

Step-by-step explanation:

No:8 Ans

A can complete the work in 12 days.

In one day he can complete 1/12th part

B can complete the work in 15 days.

In one day he can complete 1/15th part.

C can complete the work in 20 days.

In one day he can complete 1/20th part.

When they together , in one day they can complete (1/12+1/15+1/20)part.

Therefore, they will complete the work in 1/(1/12+1/15+1/20) days.

• 1/(1/12+1/15+1/20)
• 1/{(5+4+3)/60}
• 1/(12/60)
• 60/12
• 5 days.

Hence, it would take 5 days to complete the work.
