25 is related to 52 following a certain logic. Following the same logic, 36 is related to 63. To which of the following is 49 related?
94
84
74
98
94
Identify the mirror-image or digit-reversal logic where the tens digit and units digit are swapped in the given pairs.
Identify the mirror-image or digit-reversal logic where the tens digit and units digit are swapped in the given pairs.
Analyze the pattern
Observe the relationship between the pairs: 25 becomes 52 and 36 becomes 63. In both instances, the tens digit and units digit of the number are simply interchanged (or reversed).
Apply logic to the target number
To find the relation for 49, apply the same reversal logic. The digit in the tens place (4) moves to the units place, and the digit in the units place (9) moves to the tens place. 49 reversed becomes 94.
B: 84 does not follow the reversal rule (49 to 94). C: 74 does not follow the reversal rule (49 to 94). D: 98 does not follow the reversal rule (49 to 94).
A is correct because the logic applied is a simple digit reversal where the tens and units digits are swapped, transforming 49 into 94.
In number analogy questions, always check for digit operations (addition/multiplication) first, but if those fail, look for simple position-based properties like digit reversal or parity changes.
