In a certain code language, ‘MELT’ is coded as ‘54’ and ‘TAILS’ is coded as ‘66’. How is ‘SWORD’ coded in the given code language?
Sum of positional value of letters + Number of letters in the word. MELT = 13 + 5 + 12 + 20 = 50; 50 + 4 = 54. TAILS = 20 + 1 + 9 + 12 + 19 = 61; 61 + 5 = 66. SWORD = 19 + 23 + 15 + 18 + 4 = 79; 79 + 5 = 84.
