2 men and 7 boys can do a piece of work in 4 days. The same work is done in 3 days by 4 men and 4 boys. How long would it take one man and one boy to do it?

If 15 men or 24 women or 36 boys can do a piece of work in 12 days, working 8 hours a day, how many men must be associated with 12 women and 6 boys to do another piece of work 2.25 times in 30 days working 6 hours in a day?

Q. If 5 man & 9 women can do a piece of work in 19 days then in how many days will 3 men and 6 women do the same work?

If one man or 2 women or 3 boys can do a piece of work in 44 days, then the same piece of work will be done by 1 man, 1 woman and 1 boy in how many days?

The correct option is D 24 1 man = 2 woman = 3 boys ⇒1 man + 1 woman + 1 boy= (3 + 32 + 1) = 112boys 3 boys × 44 days =112 × x ⇒ x = 24

The correct option is D
24

1 man = 2 woman = 3 boys $\Rightarrow$ 1 man + 1 woman + 1 boy= $(3 + \frac{3}{2} + 1) = \frac{11}{2}$ boys

3 boys $\times$ 44 days = $\frac{11}{2} \times x \Rightarrow$ $x$ = 24
