In each of the following questions, two numbers are given which follow a certain logical or arithmetic relationship. Identify the same pattern and apply it to find the missing number in the second pair. Choose the correct option from the given alternatives.
432 : 234 :: 731 : ?
Show answer & explanation
Correct answer: A
Explanation
The pattern followed here is the reversal of the digits of the number:
• 432: Reversing the order of digits gives 234.
Similarly, applying the same rule to the second pair:
• 731: Reversing the order of digits gives 137.
Therefore, the missing number is 137.
