Question

The students of a class have a total mass of 1717kg if the average mass per student is 50.5kg find the number of students in the class

Answer 1

Step-by-step explanation:

Examples. Most solid state acids are organic acids such as oxalic acid, tartaric acid, citric acid, maleic acid, etc. Examples include oxides, which function including silico-aluminates (zeolites, alumina, silico-alumino-phosphate), and sulfated zirconia.Examples.

Answer 2

The answer is 34.

GIVEN

Total mass of students = 1717 kg

Average mass per student = 50.5 kg

TO FIND

The number of students in the class

SOLUTION

We can simply solve the above problem as follows;

Let the total number of students = x

It is given,

Total mass of students = 1717 kg

Average mass of students = 50.5 kg

We know that,

Average = Sum of all observations/total number of observation.

Therefore,

50.5 = 1717/x

Multiplying x in LHS

50.5x = 1717

x = 1717/50.5 = 34.

Hence, The answer is 34.
