Q: A woman fills a bucket in 6 minutes. 1845 buckets have to be filled from 8 am. to 9:30 am. How many woman employees should be employed for this task?

We know that, M 1 × D 1 W 1 = M 2 × D 2 W 2 Here M1 = 1, D1 = 6 min, W1 = 1 and M2 = M, D2 = 90 min, W2 = 1845 1 × 6 1 = M × 90 1845 => M = 123

Correct Answer: 123

Explanation:

We know that, $\frac{M 1 \times D 1}{W 1} = \frac{M 2 \times D 2}{W 2}$

Here M1 = 1, D1 = 6 min, W1 = 1 and M2 = M, D2 = 90 min, W2 = 1845

$\frac{1 \times 6}{1} = \frac{M \times 90}{1845}$

=> M = 123
