This question was previously asked in
RRB NTPC 2019 CBT 1 Question Paper (8-Mar-2021) (Shift 2)
The correct answer is
2 only

To solve this problem, we need to analyze the Venn diagram provided. The diagram consists of three intersecting circles representing the sets of "Teachers," "Chinese," and "Indian."

Our task is to identify the region that represents teachers who are Chinese but not Indian. This region will be the intersection of the "Teachers" circle and the "Chinese" circle, excluding any area shared with the "Indian" circle.

Looking at the Venn diagram:

  • Region 2: This is the part common to both "Teachers" and "Chinese," but it is outside the "Indian" circle. Therefore, it represents teachers who are Chinese but not Indian.
  • Region 1: This is in all three circles—"Teachers," "Chinese," and "Indian," so it includes Indians.
  • Region 3: This is inside "Chinese" and "Indian" but not in "Teachers," and hence not relevant.
  • Region 7: This is inside "Chinese" and "Indian," but it is not part of "Teachers."

Thus, the correct region representing "teachers who are Chinese but not Indian" is 2 only. This aligns with the given correct answer.

Conclusion: The correct option is 2 only.
