Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 4: 52.
The logic used here is:
(1st number)3 - (1st number)2 = 2nd number
Option 1: 5: 100
(5)3 - (5)2 = 125 - 25 = 100
This follows the logic.
Option 2: 7: 294
(7)3 - (7)2 = 343 - 49 = 294
This follows the logic.
Option 3: 6: 180
(6)3 - (6)2 = 216 - 36 = 180
This follows the logic.
Option 4: 4: 52
(4)3 - (4)2 = 64 - 16 = 48
This does not follow the logic.
Hence, option 4 is the odd one out.
