Answer 1

You've to find the "change" by getting the difference between the two numbers:

change = New - original = 90 - 85 = 5

Percent of change = 5 * 100/ 85 = 5.88 % percent of the original value.

Approximately (rounded) = 6 % of the original value.

To check the answer :

New = Original + 6 % Original ~~ 90
