Select the option that is related to the fourth number in the same way as the first number is related to the second number and the fifth number is related to the sixth number.

Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. 22.
The logic used here is:
17 : 293
172 + 4 = 289 + 4 = 293
21 : 445
212 + 4 = 441 + 4 = 445
Similarly;
? : 488
x2 + 4 = 488
x2 = 484
x = 22
Hence, the correct answer is 22.
