Answer 2

Concept: In opt for odd range try / cluster, bound pairs / teams of numbers square measure given out of that all except one square measure similar in some manner whereas one is totally different. The numbers in these similar pairs could have an equivalent property or could also be associated with one another in keeping with an equivalent rule. The candidate is needed to decide on the odd try / cluster.

Find: Choose one odd pair of numbers.

Solution:

Difference between 41 and 72

72-41= 31

Difference between 12 and 30

30-12= 18

Difference between 51 and 42

51-42= 9

Difference between 11 and 20

20-11= 9

Differences in 12-30, 51-42, and 11-20 are divisible by 3 but difference in 72-41 is not divisible by 3.

Final answer: a. 41-72
