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. |
18 : 288 11 : 111 12 : 120 13 : 143 |
11 : 111 |
The logic followed here is : (ist number) × (ist number - 2 ) = second number 18 : 288 ⇒ 18 × (18 - 2 ) = 288 11 : 111 ⇒ 11 × (11 - 2 ) = 99 ≠ 111 12 : 120 ⇒ 12 × (12 - 2 ) = 120 13 : 143 ⇒ 13 × (13 - 2 ) = 143 |
