Question
The average weight of a family of 8 members is 85 kg. If
the youngest member dies, the average weight of the family decreases by 1 kg. Find the weight of the person who died.Solution
Let the weight of the youngest member (who died) be x kg. Total weight of 8 members = 8 × 85 = 680 kg After the youngest member dies, the average weight of the remaining 7 members is 85−1 = 84 kg. So, total weight of remaining 7 members = 7 × 84 = 588 kg Now, Weight of the youngest member = Total weight of 8 members - Total weight of 7 members x = 680 − 588 = 92 kg
