Question

If 3 men or 5 boys can do a piece of work in 11 days. How long would 1 man and 2 boys take to complete the same work

Answer 1

I don't know the answer

Answer 2

1 man and 2 boys take 15 days to complete the same work

Step-by-step explanation:

3 men or 5 boys can do a piece of work in 11 days.

3 men = 5 boys

1 man = $\frac{5}{3} boys$

1 man and 2 boys =$\frac{5}{3} boys + 2 boys = \frac{5+6}{3}=\frac{11}{3} boys$

5 boys can do a piece of work in days = 11

1 boy can do a piece of work in days = 5 \times 11

$\frac{11}{3}$ boys can do a piece of work  =$\frac{5 \times 11}{\frac{11}{3}}=15$

Hence 1 man and 2 boys take 15 days to complete the same work
