Code = Sum of positional values + 5 For ROUGH: Sum of positional values: R + O + U + G + H = 18 + 15 + 21 + 7 + 8 = 69 Code = 69 + 5 = 74. For SPACE: Sum of positional values: S + P + A + C + E = 19 + 16 + 1 + 3 + 5= 44 Code = 44 + 5 = 49. Similarly, For CLERK: Sum of positional values: C + L + E + R + K = 3 + 12 + 5 + 18 + 11 = 49 Code = 49 + 5 = 54 So, the code for CLERK is 54. Hence, the correct answer is "54".
