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.
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 6 : 36.
The logic used here is: (1st number × 5) + 5 = 2nd number
2 : 15:- (2 × 5) + 5 = 15
3 : 20:- (3 × 5) + 5 = 20
5 : 30:- (5 × 5) + 5 = 30
6 : 36:- (6 × 5) + 5 = 35, This does not follow the logic.
