Four number-pairs have been given, out of which three are alike in some manner and one is different. Select the one that is different. (NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits.) 15 : 126; 27 : 234; 31 : 270; 17 : 162

17 : 162

PYQPulse · Answer

Explanation: Logic: Second no. = [(First no. × 9) - 9] Checking the given options: (1) 17 : 162 → ⇒ [(17 × 9) + 9] ⇒ (153 + 9) = 162 (2) 15 : 126 → ⇒ [(15 × 9) - 9] ⇒ (135 - 9) = 126 (3) 27 : 234 → ⇒ [(27 × 9) - 9] ⇒ (243 - 9) = 234 (4) 31 : 270 → ⇒ [(31 × 9) - 9] ⇒ (279 - 9) = 270 Here, '17 : 162' is different from the rest. Hence, the correct answer is "Option (1)".
