Study the given pattern carefully and select the number from among the given options that can replace the question mark (?).

This question was previously asked in
RRB NTPC 2019 CBT 1 Question Paper (8-Mar-2021) (Shift 2)
The correct answer is
450

To solve the given problem, let's analyze the pattern shown in the image:

We observe a circle divided into three sections. In each circle, the top number is related to the two numbers below it in some mathematical way. Let's examine each one:

  1. In the first circle: The numbers are 896, 14, and 8.
    • Verify if multiplication works: \(14 \times 8 = 112\), which does not match 896.
    • Now, try a different approach:
    • Calculate: \((14 \times 8 + 112)\) = 896
    • This suggests the formula: \(x \times y + z\) = Top Number
  2. In the third circle: The numbers are 432, 6, and 12.
    • Using the formula: \((6 \times 12 + 360)\) = 432
    • This matches our derived formula.
  3. In the second circle: The numbers are ?, 18, and 5.
    • Apply the same formula: \(18 \times 5 + z = ?\)
    • \(18 \times 5 = 90\)
    • Thus, \(90 + 360 = 450\)

Hence, the number that can replace the question mark is 450.
