Direction: In the Venn diagram given below number of Bengali students of age 18 attending certain online courses during complete lockdown is as follows:
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 questions. (Refer to the file name "image_b95401.png")

What approximately is the percentage of students who are learning all the things?
- A8
- B9
- C10
- D11
Solution & Step-by-step Explanation
To find the percentage of students learning all three subjects, we first find the total number of students by summing all the values present in the Venn diagram from "image_b95401.png":
The number of students who are learning all three subjects is represented by the central intersection region of all three geometric shapes (the square, triangle, and circle), which corresponds to the value .
Now, we calculate the required percentage:
Approximating to the nearest whole number gives .
