If DEMAND is coded as 23101421323 and ROSE is coded as 930810, then how will COLUMN be coded?

Positional value of opposite letter of D = W = 23 Positional value of E = 5 (vowel) = 5 x 2 = 10 Positional value of opposite letter of M = N = 14 Positional value of opposite letter of A = 1 (vowel) = 1 x 2 = 2 Positional value of opposite letter of N = M = 13 Positional value of opposite letter of D = W = 23 Similarly, Positional value of opposite letter of R = I = 9 Positional value of O = 15 (vowel) = 15 x 2 = 30 Positional value of opposite letter of S = H = 8 Positional value of opposite letter of E = 5 (vowel) = 5 x 2 = 10 Similarly, Positional value of opposite letter of T = G = 7 Positional value of E = 5 (vowel) = 5 x 2 = 10 Positional value of opposite letter of N = M = 13 Positional value of opposite letter of S = H = 8 Positional value of E = 5 (vowel) = 5 x 2 = 10 Positional value of opposite letter of D = W = 23
