Question : The marks obtained by 5 children in a test are as follows: 12, 14, 8, 10, and 16. What are the average marks obtained by these 5 children?
Option 1: 11
Option 2: 14
Option 3: 10
Option 4: 12
Correct Answer: 12
Solution :
The average of a set of numbers is calculated by adding all the numbers and then dividing by the count of the numbers.
Average = $\frac{\text{Sum of all the observations}}{{\text{Total number of observations}}}$
Average = $\frac{12 + 14 + 8 + 10 + 16}{5}$ = 12
Hence, the correct answer is 12.
