RRB NTPC 2019 CBT 1 Question Paper (8-Mar-2021) (Shift 2)
The correct answer is
50

The given figure has three sets of numbers arranged in a cross pattern. To find the number that replaces the question mark, we need to identify the pattern among these sets.

Let's analyze each cross pattern:

  1. First Pattern:
    The numbers are 18, 15, 20, and 25 around 78.
    Formula: \(78 = 18 + 15 + 20 + 25\).
  2. Second Pattern:
    The numbers are 8, 12, 17, and 3 around 40.
    Formula: \(40 = 8 + 12 + 17 + 3\).
  3. Third Pattern:
    The numbers are 11, 13, 16, and 10 around a missing number.
    We calculate: \(11 + 13 + 16 + 10 = 50\).

Thus, the number that replaces the question mark is 50.

Hence, option 50 is correct.
