Answer 1

Answer:

Step-by-step explanation:

A can complete work in 20 days

that is for A 20days = 1 work or

for A work done in 1 day = 1/20

similarly B work done in 1 day = 1/24

and A , B and C can do work in 1day = 1/6

so that;

A+B+C one day work =1/6 or

1/20+1/24+C=1/6

C=1/6- 1/20-1/24

this is work done by C in 1 day. take its reciprocal and total days by C is answer
