Study the following diagram carefully and answer the question given below. In the diagram, a square represents a boy and a circle represents a girl, and each student is seated on one of the three benches shown.
On which bench are there three students?
- A.
Bench I
- B.
Bench II
- C.
Bench III
- D.
Bench I or II
Show answer & explanation
Correct answer: A
Concept: In a diagram-based counting question, the total number of students seated on a given bench equals the number of distinct symbols (boys marked as squares, girls marked as circles) drawn directly under that bench's label - count every symbol in the group, regardless of gender, before comparing benches.
Bench I shows three symbols - A and E drawn as squares (boys) and D drawn as a circle (girl) - so Bench I seats three students in total.
Bench II shows two symbols - F as a square (boy) and B as a circle (girl) - so Bench II seats two students.
Bench III shows two symbols - G as a square (boy) and C as a circle (girl) - so Bench III seats two students.
Cross-check: Adding the three benches gives 3 + 2 + 2 = 7 students, which matches all seven labelled students (A, B, C, D, E, F, G) shown in the diagram - confirming every student was counted exactly once and only one bench reaches a count of three.
Therefore, Bench I is the bench with three students.
