Question : Directions: Four pairs of numbers have been given, out of which three are alike in some manner, while one is different. Choose out the odd one.
Option 1: 25 : 650
Option 2: 14 : 210
Option 3: 7 : 50
Option 4: 21 : 462
Correct Answer: 7 : 50
Solution : Let's check each option – First option: (25 : 650); (25)2 + 25 = 625 + 25 = 650 Second option: (14 : 210); (14)2 + 14 = 196 + 14 = 210 Third option: (7 : 50); (7)2 + 7 = 49 + 7 = 56 ≠ 50 Fourth option: (21 : 462); (21)2 + 21 = 441 + 21 = 462
So, the third option is different from the other three options. Hence, the third option is correct.
