Answer 2

Answer:

10/7 days

Step-by-step explanation:

A completes the work in 3 days

so he completes 1/3 work in 1 day.

B completes the work in 5 days

so he completes 1/5 work in 1 day.

C completes the work in 6 dayscompletes the work in 6 days

so he completes 1/6 work in 1 day.

so they together complete work in 1 day

= 1/3 + 1/5 + 1/6

=( 10+6+5) / 30 ( taking LCM of 3,5 & 6 )

= 21/30

= 7/10

so they complete 7/10 in 1 day so they will complete the work together in 10/7 days
