This question may seem intimidating. But if we read carefully, we can see that this can be done with a little calculation.
The answer option E.
Note: Many times students calculate all the numbers individually which makes it tedious.
- We need to find the population of males in 1993 who are not enrolled.
- Thus it is the "total male population - the number of males who are enrolled"
- Total male population = 37 + 88 = 125 million
The number of males who are not enrolled = (16% + 29%) of total enrollment = 45% of 13.9 million
- 45% of 13.9 million = 50% of 13.9 - 5% 13.9 = 7 - 0.7 = 6.3 (We can ignore the 0.05 as the answer options are 2-3 million apart so it won't create any issues)
- Thus the answer = 125 - 6.3 = 118.7
The answer option E.

Let's break this down into two simple steps.
Step 1: Find the total male population in 1993.
From the population table:
- Males Under Age 25 = 37 million
- Males Age 25 and Over = 88 million
- Total males = 37 + 88 = 125 million
Step 2: Find how many males WERE enrolled in college in 1993.
Total college enrollment in 1993 = 13.9 million.
Now look at the percentage breakdown for 1993:
- Males Under Age 25 = 29%
- Males Age 25 and Over = 16%
- Total male percentage = 29% + 16% = 45%
So, males enrolled in college = 45% of 13.9 million = 0.45 × 13.9 ≈ 6.26 million.
Step 3: Subtract enrolled males from total males.
Males NOT enrolled = 125 - 6.26 ≈ 118.74 million.
The closest answer is 119 million.
Answer: E
Key tip: Note that the enrolled number (~6 million) is tiny compared to the total population (~125 million). So the answer was always going to be very close to 125 million. This could have helped you eliminate choices A, B, and C right away, since they're too far from 125. On data-heavy GMAT questions, a quick sanity check like this can save time and prevent errors.
