Question
Average weight of all the people in a group is 60 kg.
When two people of weight 66 kg and 84 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, 60n - 59 × (n - 2) = 66 + 84
Or, 60n - 59n + 118 = 150
Or, n = 32
Required number of people = 32 - 2 = 30
