A bar chart shows the number of customers visiting a store on five days: Monday (150), Tuesday (200), Wednesday (180), Thursday (220), Friday (250). What is the percentage increase in customers from Monday to Friday?
Show Hint
- 60%
- 66.67%
- 70%
75%
The Correct Option is B
Solution and Explanation
- Step 1: Identify values. Monday: 150, Friday: 250.
- Step 2: Calculate increase. Increase = $250 - 150 = 100$.
- Step 3: Calculate percentage increase. Formula: $\left(\frac{\text{Increase}}{\text{Initial}}\right) \times 100 = \left(\frac{100}{150}\right) \times 100 = 66.67%$.
- Step 4: Verify with options. 66.67% matches option (2).
- Step 5: Cross-check. $150 \times 0.6667 = 100$, so $150 + 100 = 250$, which is Friday’s value.
- Step 6: Final conclusion. Option (2) 66.67% is the correct answer.
