Answer 1

Answer:

25 days

Step-by-step explanation:

(A+B+C) - 10Day - 1work

1 day - 1/10 work

4 days- 4/10 work=2/5

Remaining work done by B and C in 10 days is

1-2/5=3/5 unit

B+C - 10 days - 3/5 unit

B+C - 1 work - 10÷3/5 = 50/3days

B+c - 1day work 3/50 unit

A's 1 work -

(A+B+C) 1 day work-(B+C) 1 day work

1/10-3/50=1/25

A can complete in 25 days.
