Question

A can do in 12 day , and B can do in 10 and A,B,C can di in 4 day in how many day can C in how many day
​

Answer 1

Answer:

15 days

Step-by-step explanation:

A can complete the job in 12 days hence completes 1/12 work per day

B can complete the job in 10 days hence completes 1/10 work per day

now with the help of C they complete the Job in 4 days

Hence

work done by C = Total work done in 4 days - work done by A - work done by B

C = 1- 4/12–4/10

C = 0.26 in 4 days

hence C completes 0.26/4 work in one day =0.0667

to complete 100% work C will take 1/ work done per day = 15 days
