Here the logic is (Sum of the position of letters of word) - (Number of letters in the word) S = 19 I = 9 N = 14 K = 11 Number of letters in the word = 4 = (19 + 9 + 14 + 11) - (4) = 53 - 4 = 49 Similarly, C = 3 R = 18 A = 1 F = 6 T = 20 Number of letters in the word = 5 = (3 + 18 + 1 + 6 + 20) - (5) = 48 - 5 = 43 Similarly, P = 16 R = 18 I = 9 N = 14 T = 20 Number of letters in the word = 5 = (16 + 18 + 9 + 14 + 20) - (5) = 77 - 5 = 72 Hence, the correct answer is "72".
