The average weight of 4 persons is increased by 14kg when one of them whose weight is 55kg, is replaced by another person. What is the weight (in kg) of the new person?
- A111
- B85
- C56
- D98
Solution & Step-by-step Explanation
Given:
Number of persons = 4
Increase in average weight = 14kg
Weight of the replaced person = 55kg
The total increase in weight across all 4 persons is:
Total Increase=4×14=56kg
The weight of the new person can be calculated as:
Weight of new person=Weight of replaced person+Total Increase
Weight of new person=55+56=111kg
Therefore, the weight of the new person is 111kg.
Number of persons = 4
Increase in average weight = 14kg
Weight of the replaced person = 55kg
The total increase in weight across all 4 persons is:
Total Increase=4×14=56kg
The weight of the new person can be calculated as:
Weight of new person=Weight of replaced person+Total Increase
Weight of new person=55+56=111kg
Therefore, the weight of the new person is 111kg.
