Question

Out of the given number pairs, three are similar in a certain manner. However, one pair is NOT like the other three. Select the pair which is different from the rest
1. 225 : 3375
2. 49:280
3. 64:512
4. 25:125

Answer 1

Correct Answer - Option 2 : 49:280

The logic is:

the pattern being followed here is:

(Number)² : (Number)³

1. 225 : 3375 → 15² : 15³

2. 49 : 280 → 7² : 7³ = 343 ≠ 280

3. 64 : 512 → 8² : 8³

4. 25 : 125 → 5² : 5³

Hence, ‘49 : 280’ is the odd one out.
