Question

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 average number of customers per day?

• A. 190
• B. 200
• C. 210
• D. 220
  \bigskip

Hint:

For average calculations, sum all values and divide by the number of data points, ensuring accurate summation.

Answer 1

The Correct Option is B

- Step 1: Sum the customers. Monday: 150, Tuesday: 200, Wednesday: 180, Thursday: 220, Friday: 250. Total = $150 + 200 + 180 + 220 + 250 = 1000$. 
- Step 2: Calculate average. Number of days = 5. Average = $1000 \div 5 = 200$. 
- Step 3: Verify with options. 200 matches option (2). 
- Step 4: Cross-check. Recalculate: $1000 \div 5 = 200$. 
- Step 5: Final conclusion. Option (2) 200 is the correct answer.
