1. In a boat there are 8 men whose average weight is increased by 1 kg when 1 man of 60 kg is replaced by a new man. What is weight of new comer?

Solution:
Member in group × age increased = difference of replacement
Or, 8 × 1 = new comer - man going out
Or, new comer = 8 + 60
Or, new comer = 68 kg.
