The table shows weekly sales (in units) at a shop.Item Units sold Coffee 150 Butter 30 Bread 100 Eggs 20
What percentage of the total units sold was butter?
Answer and explanation
Correct answer: C. 10%
- Step 1: Total units = 150 + 30 + 100 + 20 = 300. Step 2. 30 / 300 x 100 = 10%. Answer: 10%. Why not the others: 11.11% divides by the other three items (270) instead of the total (300); 20% divides by the largest single item (150) instead of the total; 90% is the share of all the other items, not of butter.
