Question : Directions: In the following question, select the one which is different from the other three alternatives.
Option 1: 144
Option 2: 125
Option 3: 343
Option 4: 64
Correct Answer: 144
Solution : Let's check the options – First option: 144; 144 is not a perfect cube. Second option: 125; 125 = 5 3 ; 125 is a perfect cube. Third option: 343; 343 = 7 3 ; 343 is a perfect cube. Fourth option: 64; 64 = 4 3 ; 64 is a perfect cube.
So, the first option is different from others as the 144 is a perfect square, not a perfect cube. Hence, the first option is correct.
