A pie chart shows 40% segment A and 60% segment B, with a total of 200 units. How many units are in segment B?

• A. 120
• B. 80
• C. 140
• D. 60

Answer: (A)

Understanding percentages of a total: segment B makes up 60% of the whole 200 units. Multiply 200 by 0.60 to find its quantity: 200 × 0.60 = 120 units. A quick check shows segment A is 40% of 200, which is 80 units, and 80 + 120 = 200, so the breakdown is consistent. The other numbers would correspond to different percentages (for example, 80 is 40% of 200, 140 is 70% of 200, and 60 is 30% of 200), so they don’t match segment B. The correct amount for segment B is 120 units.
