Question

Study the given pattern carefully and select the number that can replace the question mark (?) in it

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

13

To solve the problem, let's examine the pattern in each circle. We need to find the relationship between the numbers outside the circle and the number inside it.

  1. In the first circle, observe the numbers: 12, 10, 5, and 7. The sum of these numbers is calculated as follows: \(12 + 5 + 7 = 24\). By subtracting the number inside the circle from this sum, we get \(24 - 10 = 14\).
  2. Apply the same pattern to the second circle: 16, 11, 4, and 8. The sum of these numbers is: \(16 + 4 + 8 = 28\). Subtracting the number inside gives: \(28 - 15 = 13\).
  3. Let's check this pattern against the third circle. The numbers given are 15, 9, 5, and 6. The sum is: \(15 + 9 + 6 = 30\). Subtracting the sum from the central number gives: \(30 - 13 = 17\). This confirms that the number in the third circle should be 13, which satisfies the relationship.

Therefore, the number that replaces the question mark is 13.
