The table shows weekly sales (in units) at a shop.Item Units sold Coffee 80 Bread 100 Pasta 40 Milk 100
What percentage of the total units sold was coffee?
Answer and explanation
Correct answer: B. 25%
- Step 1: Total units = 80 + 100 + 40 + 100 = 320. Step 2. 80 / 320 x 100 = 25%. Answer: 25%. Why not the others: 33.33% divides by the other three items (240) instead of the total (320); 80% divides by the largest single item (100) instead of the total; 75% is the share of all the other items, not of coffee.
