Answer 1

Answer:

the answer is 385/12days

Step-by-step explanation:

11 m+8 w can do 1/5 in one day

11b+3 w can do 1/7 in one day

add: 11 m+11 w+11 b can do 12/35 in one day

so 1 m +1 w+1 b can do 12/(35*11) in one day

so the answer is 385/12 days

Answer 2

Answer:

2) 30 days

Step-by-step explanation:

11 M + 8 W = 5 days

1 day --- 1/5 units

11 B + 3 W = 6 days

1 day ----. 1/6 units

Adding both eq.

11 M + 11 w + 11B = 1/5+1/6

11(M+w+B) = 11(1/30)

M+W+B = 1/30 Units

So, M+W+B= 30 days
