Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 60.6 kg.
Total weight of 14 persons = 75 × 14 = 1050 kg
Let the average weight of all 16 persons = x
So, 16x - 1050 = x + 48
⇒ 15x = 1098
⇒ x = 1098/15 = 73.2 kg
Remaining two persons' total weight = 16 × 73.2 - 1050 = 1171.2 - 1050 = 121.2 kg
Average weight of the remaining two persons = 121.2/2 = 60.6 kg
