Question 60

In a circle team of eleven players, one player weighing 42 kg, is injured and his place is taken by another player. If the average weight of the team is increased by 100 grams as a result of this, then the weight of the new player is--

Solution

Let the weight of the new player be x kgs.

Total weight as a result of his inclusion = TW - 42 + x

Average weight = (TW - 42 + x)/11

But average weight before = TW/11

(TW - 42 + x)/11 - TW/11 = .1

x - 42 = 1.1

So, x = 43.1 kgs
