The arithmetic mean of x and y is greater than 20
What is Arithmetic mean?
In mathematics and statistics, the arithmetic mean or arithmetic average, or simply just the mean or the average, is the sum of a collection of numbers divided by the count of numbers in the collection.
Given,
Arithmetic mean of 2x and 4x is 48
Then,
[tex]\frac{2x+2y}{2}=48\\ 2x+2y=96\\2(x+y)=96\\x+y=48\\[/tex]
then, the arithmetic mean of x + y = [tex]\frac{48}{2} =24[/tex]
Hence, the arithmetic mean of x and y is greater than 20
