Correct Answer - Option 3 : 14
The logic followed here is:
First number multiply with (first number - 1) and add with subtraction between first number and 8 and so on.
12 : 136 : : ? : 188 : : 24 : 568
For 12 : 136;
12 × 11 + (12 - 8) = 132 + 4 = 136, and
For 24 : 568;
24 × 23 + (24 - 8) = 552 + 16 = 568
Similarly,
For ? : 188;
? × (? - 1) + (? - 8) = 188
?2 - ? + ? - 8 = 188
?2 - 8 = 188
?2 = 196
? = 14
Hence, "option 3" is the correct answer.
