The second number in the given number pairs is obtained by performing a certain mathematical operation on the first number. The same operation(s) are followed in all the number pairs, EXCEPT one. Find that odd number pair.
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 520 : 481.
The logic used here is: 1st number - 2nd number = 29
Option 4: 520 : 481: 520 - 481 = 39: This does not follow the logic.
