Answer 2

Given - average weight of 20 people is increased by 2.2kg

Weight of original man = 53 kg

Find - Weight of new man

Solution - Firstly calculating value of increased weight = 20*2.2

Increased weight = 44 kilograms

Now, calculating weight of new man.

To calculate the weight of new man, we will simply add the increased weight to the weight of man replaced.

Hence, weight of new man = 53 + 44

Weight of new man = 97 kilograms

Hence, the weight of new man is 97 kilograms.
