The second number in the given number-pairs is obtained by performing certain mathematical operation(s) on the first number. The same operation(s) are followed in all the number-pairs EXCEPT one. Find that odd number-pair.
Explanation:
The logic is: 2nd number = Square-root of 1st number - 2.
Option (a): 3 = √25 - 2 = 5 - 2 = 3 Option (b): 6 = √64 - 2 = 8 - 2 = 6 Option (d): 7 = √81 - 2 = 9 - 2 = 7
Option (c) does not follow this rule.
Hence, option (c).
