Thanks.Explanation / Answer
this is one of those estimation problems.... a persons mass would most probably be about 60-70 kilos So if you take the average of 60 and 70, you'll get 65kilos Hence, on average each person will have mass of 65kgs. Since thereare 150 students 150 students * 65kgs/student = 9750 kilos which is about104 kilos for all the students
