Select the option in which the numbers share the same relationship as that shared by the given pair of numbers.
(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.)
17 : 253
19 : 271
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 21 : 289.
17 : 253 → (17 × 9) + 100 = 153 + 100 = 253
19 : 271 → (19 × 9) + 100 = 171 + 100 = 271
Similarly, 21 : 289 → (21 × 9) + 100 = 189 + 100 = 289
