Which Character is needed to replace the question mark segment
Answer : 15
In each circle, the lower left value equals the sum of the numeric values of letters and top right value equals the difference in the letter values.
Assign 1 to 26 numbers to A to Z alphabets.
In first circle, G = 7 and P = 16. So, 7 + 16 = 23 which is in left bottom and 16 – 7 = 9 which is in top right.
Similarly in third circle difference between T and E is 15.
So, answer 15.
