The price of a bag of maize rose from KSh 40 to KSh 50. What is the percentage change?
Answer and explanation
Correct answer: D. 25% increase
- Step 1: Change = 50 - 40 = 10. Step 2. Percentage change = change / original x 100 = 10 / 40 x 100 = 25%. Answer: 25% increase. Why not the others: 20% increase: That divides by the new price instead of the original price. 25% decrease: That has the right size but the wrong direction. 10% increase: That treats the shilling difference as a percentage.
