Total weight limit: 630

Heaviest weighs: 101 kg and the lightest weighs: 53 kg

For the maximum number of possible people, the weigh of those people should be as low as possible but greater than 53.

630 - (101 + 53 = 154) = 476

For remaining fo 476 kg weight, we can have maximum 8 people [60 * 8 = 480]. Total number of people: 2 + 8 = 10

Weight remaining after removing the heaviest and the lightest person, = 630-101-53 = 476kg.

To maximize the number of people, we'll have to consider the weight just above the lightest person's weight.

60*7 = 420
Remaining weight = 56

A total of 10 persons

C is the answer

I get the logic which is to use the lowest possible weight, but how is 476/53 = ~8 when it should be 9? In which case the answer is 11.
