Correct Answer: 2 : 10


Solution : Let's check the options –
First option: 5 : 45; 5 + 2 = 7 and 7 2 – 2 2 = 49 – 4 = 45
Second option: 2 : 10; 2 + 2 = 4 and 4 2 – 2 2 = 16 – 4 = 12 ≠ 10
Third option: 3 : 21; 3 + 2 = 5 and 5 2 – 2 2 = 25 – 4 = 21
Fourth option: 4 : 32; 4 + 2 = 6 and 6 2 – 2 2 = 36 – 4 = 32

So, only the second option does not follow the pattern of the other three options. Hence, the second option is correct.
