Question

25 men can wash 150 machines in 3 days.if there are 200 machines to be washed,how many days will 30 men take to wash them?

Answer 1

100/3 days = 33.33 days will be taken to wash the machines.

Answer 2

Answer:

4 days

Step-by-step explanation:

We are given that 25 men can wash 150 machines in 3 days

We are supposed to find if there are 200 machines to be washed,how many days will 30 men take to wash them?

Formula : $\frac{M_1 \times D_1}{W_1} =\frac{M_2 \times D_2}{W_2}$

$M_1=25\\D_1=3\\W_1 =150$

$M_2=30\\D_2=?\\W_2=200$

Substitute the values in the formula

$\frac{25 \times 3}{150} =\frac{30 \times D_2}{200}$

$\frac{25 \times 3 \times 200}{150 \times 30} = D_2$

$3.33= D_2$

So, it will take 4 days for 30 men  to wash 200 machines.
