Answer:
Option d is the odd one.
Last pair 81-36 doesn't belong with others.
Step-by-step explanation:
Observe all the pairs.
All the pairs are ascending in orders expect the last one.
21< 49
24< 64
25< 54
but 81> 36
Therefore only 81-36 is the pair which is descending. Therefore it is the odd one.
Generally, in such type of Questions always observe properly and find the difference between first and second term, some pattern will be seen.
49-21 = 28
64-24= 40
54-25= 29
36-81= -45
As we can see only the last pair has negative difference.
So pair 81-36 or option d does not belong with others.
