The average weight of a group of 15 students increases
by 1.5 kg when the weight of the teacher is also included. If earlier the average weight of the group was 55 kg, then find the weight of the teacher.Solution
ATQ, Total weight of the group (Excluding the weight of the teacher) = 15 × 55 = 825 kg New total weight of the group = 16 × (55 + 1.5) = 16 × 56.5 = 904 kg So, weight of the teacher = 904 - 825 = 79 kg
