Answer:
Sample average can be expressed as x¯¯¯=∑xin for n inputs. For 4 different numbers a,b,c,d, the average works up as x¯¯¯=a+b+c+d4.
We have to find 4 different numbers whose average works up to 50.
We take 31, 66, 57, 46. We now try to find the average.
So, the sum is 31+66+57+46=200.
The average will be 200/4=50.
Therefore, the average of 4 different numbers 31, 66, 57, 46 is 50.
So, the correct answer is “31, 66, 57, 46”.
