Direction: Refer to the Venn diagram in the given image image_b9b8db.png showing the number of Bengali students of age 18 attending certain online courses during complete lockdown:
The square represents the students who are learning Spanish, the triangle is for those who are learning music, and the circle is for those who are learning photography. Study the diagram and answer the question.
What approximately is the percentage of students who are learning only two things?
- A41
- B42
- C43
- D44
Solution & Step-by-step Explanation
From the Venn diagram provided in
* Students learning only two things are found in the regions where exactly two shapes intersect, excluding the central region where all three intersect:
* Spanish and Photography only = 45
* Spanish and Music only = 15
* Music and Photography only = 40
* Total number of students represented in the entire Venn diagram:
* Percentage calculation:
Rounding 41.67% to the nearest whole number gives approximately 42.
