Which age category has the smallest percentage among the listed age groups?

• A. 19-30 years
• B. Under age 12 (15%)
• C. Over age 30
• D. 12-18 years

Answer: (B)

When you’re looking at a distribution across age groups, the key idea is to identify which group has the smallest share by comparing the percentage values attached to each category.

In this item, the under-12 category is labeled with 15%. That explicit figure is lower than the numbers implied or given for the other age ranges, so it represents the smallest portion of the population among the listed groups. The other categories don’t present a smaller percentage in the prompt, so the under-12 group stands out as the least represented. In practice, you would always compare the actual percentages shown for each category, and the smallest one indicates the answer.
