- 61Kg.
Average weight of 24 students = 36Kg.
Average weight of 25 including teacher = 37Kg.
So teacher's weight = (37*25) - (36*24) = 925 - 864 = 61Kg. - 13 years agoHelpfull: Yes(13) No(1)
- Number * Average = Sum
=>For 24 Students - 24*36 = 864
=>For 24+1 including teacher - 25*37 = 925
=> Average weight of the teacher = 925 - 864 = 61kg - 9 years agoHelpfull: Yes(2) No(0)
- 25*37-26*36=61
- 9 years agoHelpfull: Yes(1) No(0)
- not 36 years its 36 kg.
teacher's weight should be 36kg for remains avg constant . now for the increment in avg by 1 so it should be 25 kg
so the weight of teacher is 25+36=61kg - 9 years agoHelpfull: Yes(1) No(0)
