Explanation

Given Data:

• 15 men can manufacture 27 baskets in 1 hour (60 minutes).
• We need to find how many baskets 45 men can manufacture in 40 minutes.

Step 1: Baskets manufactured by 1 man in 1 minute

In 1 hour (60 minutes), 15 men manufacture 27 baskets.

Therefore, the number of baskets manufactured by 1 man in 1 minute is:

27 baskets/15 men×60 minutes​ =2/900

$$=0.03\text{ baskets per man per minute}.$$

Step 2: Baskets manufactured by 45 men in 40 minutes

If 1 man manufactures 0.03 baskets per minute, then 45 men will manufacture in 40 minutes:

$$45\times 40\times 0.03=54\text{ baskets}.$$
