Question

The table below shows the number of students (in hundreds) enrolled in five different colleges over four years.

In 2023, if 60% of the students in College D and 50% of those in College E were female students, what was the total number of male students (in hundreds) in these two colleges in 2023?

1. A. 18.0 (Correct answer)
2. B. 20.5
3. C. 22.5
4. D. 23.0

Correct Answer

Option A — 18.0

Detailed Solution & Explanation

The correct answer is 18.0.

Key Points

• Read the 2023 column: College D has 25 (hundred) students and College E has 16 (hundred).
• In College D, 60% are female, so males = 40% of 25 = 10 hundred.
• In College E, 50% are female, so males = 50% of 16 = 8 hundred.
• Total male students = 10 + 8 = 18.0 hundred.

Additional Information

• The figures are already *in hundreds*, so the answer stays in hundreds — no conversion is needed, and 18.0 is the intended form.
• Note the question gives the female percentages; the common error is to apply 60% and 50% directly and obtain 15 + 8 = 23, which is why 23.0 appears as a distractor.
