The other number if the average of two numbers is 41 and one is 27 is 55
<h3>How to calculate the average of numbers?</h3>
Average of number is also known as the mean.
Let the unknown number be "x" such that:
x +27/2 = 41
Determine the value of x
x + 27 = 2(41)
x + 27 = 82
x = 82 - 27
x = 55
Hence the other number if the average of two numbers is 41 and one is 27 is 55
