13 is related to 117 following a certain logic. Following the same logic, 23 is related to 207. To which of the following is 51 related, following the same logic? (NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits. E.g. 13 – Operations on 13 such as adding /deleting /multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed)
459
Observing the pattern:
- 13 is related to 117
- 23 is related to 207
Identifying a possible mathematical operation:
Multiply the given number by 9 and then add 0 (to maintain the pattern).
- (13 × 9) = 117
- (23 × 9) = 207
Applying the same pattern to 51:
- (51 × 9) = 459
Thus, the correct answer is Option 2: 459.
