Question : Directions: Four sets of numbers are given out of which three are alike in a certain way and one is different. Select the set of numbers that is different from the rest.
Option 1: 5 – 25 – 225
Option 2: 6 – 36 – 216
Option 3: 9 – 81 – 729
Option 4: 3 – 9 – 27
Correct Answer: 5 – 25 – 225
Solution :
Let's check each option –
First option:
5 – 25 – 225; (5)
2
= 25; (5)
3
= 125 ≠ 225
Second option:
6 – 36 – 216; (6)
2
= 36; (6)
3
= 216
Third option:
9 – 81 – 729; (9)
2
= 81; (9)
3
= 729
Fourth option:
3 – 9 – 27; (3)
2
= 9; (3)
3
= 27
So, only the first option doesn't follow the same pattern as followed by the other options. Hence, the first option is correct.
