This question was previously asked in
RRB NTPC 2019 CBT 1 Question Paper (8-Mar-2021) (Shift 2)
The correct answer is
6

To solve the pattern problem, let's analyze each pentagon individually:

  1. In the first pentagon:
    • The numbers are: 2, 1, 1, 1, 1.
    • Notice that the sum of these numbers is 2 + 1 + 1 + 1 + 1 = 6.
  2. In the second pentagon:
    • The numbers are: 8, 3, 10, 9, and a missing number (?).
    • The sum of the given numbers is 8 + 3 + 10 + 9 = 30.
    • If we apply the same logic as before, the total sum should also be 36 (since 6 x 6 = 36).
    • Therefore, the missing number is 36 - 30 = 6.
  3. In the third pentagon:
    • The numbers are: 6, 9, 5, 8, 2.
    • The sum of these numbers is 6 + 9 + 5 + 8 + 2 = 30.

Therefore, the missing number which should replace the question mark is 6. Among the given options, 6 is the correct choice.
