General Studies · Coding-Decoding

Based on the letter-code mappings and conditions provided, find the correct combination for the group of letters: HMADA. Letter Codes: M = 8, J = 4, R = @, A = 9, D = c, B = 1, W = 2, Z = $, P = 3, E = #, I = 5, H = 6, G = %, U = 7, K = * Conditions: (i) If both the first and last letters are vowels, then their combinations should be interchanged. (ii) If the first letter is a consonant and the last letter is a vowel, then both should be coded with the symbol/number for the last letter (the vowel). (iii) If the first letter is a vowel and the last letter is a consonant, then both should be coded with the symbol/number for the first letter (the vowel).
