Comprehension: The following table shows the proportion of students passed in three different Graduation Streams, namely, Arts, Science and Commerce, from seven different cities A-G, along with the ratio of Males (M) to Females (F) for the three streams among the students. Based on the data in the table, answer the questions that follow.City-wise details of Graduating students.
If the number of students who passed in Commerce from City-F is 3240, then the number of students who passed from City-F is ____ % of the number of Science students who passed from City-F.
- A.
75
- B.
150
- C.
180
- D.
225
Attempted by 14 students.
Show answer & explanation
Correct answer: D
Given that 3240 students passed in Commerce from City-F and the male-to-female ratio is 16:11, total parts = 27. So, each part = 3240 ÷ 16 = 202.5.
Total students from City-F = 27 × 202.5 = 5467.5, which is not a whole number—impossible for student count. This inconsistency suggests an error in the data or assumptions.
However, assuming the ratio is correct and total Commerce students are 3240 (16 parts), then Science students must be derived from the same ratio or data. Since the answer is given as 225%, it implies total students are 2.25 times Science students.
If we reverse-engineer: suppose Science = x, then total = 2.25x. But without actual data on Science students from the table, we can't verify.
The correct answer is 225% (Option D) based on the assumption that total students are 2.25 times Science students, but this contradicts the given ratio unless other data is used.
Distractors A (75%) and B (150%) are too low, while C (180%) is closer but still under 225%.
The key point: the ratio leads to non-integer students, so data may be flawed.
But if we accept 225% as correct, it implies total students are 2.25× Science students.
