Question : Directions: Four groups of numbers have been given, out of which three are alike in some manner and one is different. Select the group that is different.
Option 1: 17 : 102 : 204
Option 2: 12 : 72 : 144
Option 3: 14 : 90 : 180
Option 4: 26 : 156 : 312
Correct Answer: 14 : 90 : 180
Solution : Let's check each option – First option: 17 : 102 : 204; 17 × 6 = 102 and 102 × 2 = 204 Second option: 12 : 72 : 144; 12 × 6 = 72 and 72 × 2 = 144 Third option: 14 : 90 : 180; 14 × 6 = 84 ≠ 90 and 90 × 2 = 180 Fourth option: 26 : 156 : 312; 26 × 6 = 156 and 156 × 2 = 312
So, the third option is different from the other three options. Hence, the third option is correct.
