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, 53
Option 2: 19, 39
Option 3: 37, 75
Option 4: 68, 137
Correct Answer: 25, 53
Solution :
Let's check each option –
First option:
25, 53; 25 × 2 + 1 = 51 ≠ 53
Second option:
19, 39; 19 × 2 + 1 = 39
Third option:
37, 75; 37 × 2 + 1 = 75
Fourth option:
68, 137; 68 × 2 + 1 = 137
So, the first option is different from the other three options as here the resultant is 51 instead of 53. Hence, the first option is correct.
