Imagine Prema have 50, so if he had 10 more. It would be 60. And if he had 6 lesser , it would be 44. So the difference is 16.
So the difference in 16 cause a difference of 2 in the average. So to find the number of people, you have to divde (total / number of people = average)
16 / ? = 2
? = 8
Do give me a feedback if you understand.
