The average weight of 4 persons is increased by 14 kg when one of them whose weight is 55 kg, is replaced by another person.
Formula used:
New person's weight = Old person's weight + Increase in total weight
Calculation:
Increase in average weight = 14 kg
Number of persons = 4
Total increase in weight = 14 × 4 = 56 kg
Old person's weight = 55 kg
⇒ New person's weight = 55 + 56
⇒ New person's weight = 111 kg
∴ The correct answer is option 1.
