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

To solve this logical reasoning problem, we need to identify the pattern in the given figure and apply it to find the number that replaces the question mark (?).

Let's analyze each figure step by step:

  1. The top number in each stick figure can be determined by operations involving the other numbers in that figure.
  2. For the first figure:
    • Numbers: 8, 4 (horizontal), 12, 10 (bottom).
    • Top number: 10.
    • Checking pattern: Subtract the smallest number at the bottom from the sum of horizontal numbers. \((8 + 4 - 2 = 10)\).
  3. For the second figure:
    • Numbers: 15, 2 (horizontal), 9, 16 (bottom).
    • Top number: 5.
    • Pattern: Subtract the smallest number at the bottom from the sum of horizontal numbers. \((15 + 2 - 12 = 5)\).
  4. Now apply the pattern to the third figure:
    • Numbers: 5, 6 (horizontal), 20, 2 (bottom).
    • Apply pattern: \((5 + 6 - 3 = 8)\).

Thus, the number that replaces the question mark is 8.

Therefore, the correct answer is:

8
