Question 53

A production count rises from 120 to 150. Which method does NOT calculate its percent change correctly?

  1. 30 / 120 x 100
  2. 150 - 120 = 30, then 30 / 120 x 100
  3. 30 / 150 x 100Bonne réponse
  4. Use the old value 120 as the base.

Explication

The calculation 30 / 150 x 100 = 20% uses the new count as the base, so it is not the correct method. The change is 30 and the old base is 120, giving 30 / 120 x 100 = 25%.
