Y = 41.
X = 81
5 + 7 + 28 + x + 4x + y = 6x
40 + 5x + y = 6x
40 + y = x
40 + 41 = 81

40 + 5x + y = 6x
40 + y = x
40 + 41 = 81

AS per the question, we need to calculate the Average of the given numbers. So,
(7 + 5 + 28 + x + 4x + y ) / 6 = x
Simplifying, we get 40 + y = x
Examine the values of x and y. We see that only when y = 41, we get another element - 81 - which is present in the given list.
SO, y = 41 and x = 81.
(7 + 5 + 28 + x + 4x + y ) / 6 = x
