Answer 2

Answer:

The weight of new man is 132 kg.

Step-by-step explanation:

Here, the increment in average weight of 4 men = 3,

Thus, the total increment in the total sum of weight of men = 3 × 4 = 12 kg,

Since, the weight of replaced man = 120 kg,

Thus, the weight of new man = the weight of replaced man  + total increment in the total sum of weights

= 120 + 12

= 132 kg.
