We can use the formula for the union of two sets to find the value of n(A U B):
n(A U B) = n(A) + n(B) - n(AB)
Substituting the given values, we get:
80 = (20 + 4x) + (8x - 10) - 2x
Simplifying the equation, we get:
80 = 30x + 10
70 = 30x
x = 7/3
Since x is a certain whole number, this must be a mistake in the question or the values provided. However, if we assume that x is a whole number, we get:
x = 2
Substituting x = 2 in the given values, we get:
n(A) = 28
n(B) = 6
Therefore, the value of n(A) is 28 and the value of n(B) is 6.
