Correct Answer

Explanation

The weight of the new man is 40 kg.
To find this, we can use the following steps:
The average decrease in weight per person is 2 kg.
The total number of men is 10, so the total decrease in weight when one of them is replaced by a new man is 10 * 2 = 20 kg.
The weight of the man who is replaced is 60 kg.
Therefore, the weight of the new man is 60 - 20 = 40 kg.
