Answer 1

Answer:

7 1/2 days

Step-by-step explanation:

Given,

A, B and C can finish a job in 2 hours.

A+B+C=1/2

If A alone can finish the job in 5 hours, B alone finishes

in 6 hours,

A=1/5 B=1/6

how long will it take for C to finish the job alone? ​

C=1/2-A-B

C=1/2-1/5-1/6

C=15-6-5/30

C=4/30

C=7.5 days
