What is D's share as a percentage?

• A. 15%
• B. 25%
• C. 40%
• D. 20%

Answer: (D)

The main idea is turning a part of the whole into a percent. A percentage shows what portion of the total you have out of 100. If D’s portion is one-fifth of the total, then as a percent that’s (1/5) × 100 = 20%. So 20% is the correct choice because one-fifth equals twenty percent. The other numbers represent different fractions: 15% is 3/20, 25% is 1/4, and 40% is 2/5, which would describe shares other than one-fifth. If you imagine the total as 100 units, D would have 20 units, confirming 20%.
