FOLLOWED here is,Take Z = 1, Y = 2, X = 3, ....... A = 26Each alphabet's inverse POSITIONAL value has been written and Each vowel has been given the sequence A - 1, E - 2 , I - 3, O - 4, U -5. Using this pattern SYNTAX will be CODED as :S = 8Y = 2N = 13T = 7A = 1X = 3Therefore the code for SYNTAX is 8213713And for MOULD is as, M = 14O = 4U = 5 L = 15D = 23MOULD = 14461523Similarly,Code for DESIGN is as:D = 23E = 2S = 8I = 3 G = 20N = 13DESIGN is coded as 232832013.Hence, option 1 is the correct answer.
