Correct Answer: 273
Solution :
Given:
11 : 133 :: 16 : ? :: 22 : 507
Square the first number and then add 1 and the first number to the resultant, to get the second number –
Like, 11 : 133→(11)
2
= 121; 11 + 1 = 12; 121 + 12 = 133
And, 22 : 507→(22)
2
= 484; 22 + 1 = 23; 484 + 23 = 507
Similarly, follow the same pattern for 16 : ?→(16)
2
= 256; 16 + 1 = 17; 256 + 17 = 273
So, the missing number is 273. Hence, the third option is correct.
