Question
Average weight of 5 students in a class increases by 4
kg when weight of teacher is also included. If sum of average weight of 5 students and weight of teacher is 104 kg. Find the weight of teacher?Solution
Let the average weight of class be x. and weight of teacher be t. so, Total weight of 5 students = 5x Now, average weight is also included then, (5x + t)/6 = x + 4 5x + t = 6x + 24 t – x = 24 t = x + 24------(i) AQT, x + t = 104 2t – 24 = 104 t = 64
