Question

Study the given pattern carefully and select the numbers from among the given options that would be most appropriate for replacing 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
$2, 10$

To solve the pattern and find the numbers that can replace the question marks, we need to observe the given sequences:

We have the following patterns:

  • First pattern: \(2, 6 \rightarrow 12\)
  • Second pattern: \(2, 8 \rightarrow 16\)
  • Third pattern: \(?, ? \rightarrow 20\)

Looking at the known patterns:

  • First, multiply the numbers: \(2 \times 6 = 12\)
  • Second, multiply the numbers: \(2 \times 8 = 16\)

The pattern appears to multiply the two numbers to give the result inside the circle.

To determine the numbers for the third pattern that results in 20, solve for \(x \times y = 20\).

  • Try the options:
    • Option 1: \(5 \times 4 = 20\) but doesn't match the expected pattern.
    • Option 2: \(4 \times 5 = 20\) but doesn't match the design pattern logic.
    • Option 3: \(2 \times 10 = 20\), matches the pattern (factors of 2 used consistently).
    • Option 4: \(10 \times 2 = 20\), same logic as above.

Therefore, the correct numbers are 2, 10, which follows the established pattern logic of using 2 as a consistent factor.
