Question

10. What is the percentage change when :
(1) 25 is increased to 45​

Answer 1

Answer:

Percent change = (45 - 25)/25 × 100% = 20

20/25 × 100 = 80% (increase)

Where: 25 is the old value and 45 is the new value. In this case we have a positive change (increase) of 80 percent because the new value is greater than the old value.
