Question
Average weight of all the people in a group is 62 kg. When
two people of weight 68 kg and 82 kg left the group, average weight reduces by 1 kg. Find the number of people in the group now.Solution
Let the number of people initially be 'n'.
So, 62n - 61 × (n - 2) = 68 + 82
Or, 62n - 61n + 122 = 150
Or, n = 28
Required number of people = 28 - 2 = 26
