Answer:58

Explanation:

Average Weight of 11 members equal to 42

Let the total weight of the students be X

X/11=42

X=42×11

=462

As one player is added the total becomes 12

Consider the new weight equal to y

given average weight after one member is added is equals to 42.5

Y by 12 is equals to 42.5

X =42.5 ×12 is equals to 520

Y-X=weight of the new player

520 - 462
