Question : Directions: In the following question, find the odd number pair from the given alternatives.
Option 1: 1 : 8
Option 2: 27 : 64
Option 3: 125 : 218
Option 4: 343 : 512
Correct Answer: 125 : 218
Solution :
Let's check the options –
First option:
1 – 8→1
3
= 1; 2
3
= 8
Second option:
27 – 64→ 3
3
= 27; 4
3
= 64
Third option:
125 – 218→ 5
3
= 125; 6
3
= 216 ≠ 218
Fourth option:
343 – 512→ 7
3
= 343; 8
3
= 512
So, the third option is different from the other three options as the second number is not a perfect cube of consecutive natural numbers. Hence, the third option is correct.
