Coding Decoding Test - 17

A number comes in place of the vowels and other letters move one step forward. The number is assigned to the vowel according to the order of the vowel. Therefore, the code for ACID will be 1D3E.

Clearly, we have:

So, INDIAN = I + N + D + I + A + N
= 17 + 27 + 7 + 17 + 1 + 27 = 96

Clearly, each letter is coded by the numeral denoting its position in the English alphabet.
Thus, A is coded as 1, B as 2, C as 3, D as 4, ..., L as 12, M as 13, …, Y as 25, and Z as 26.

So, the code for LADY is 12 – 1 – 4 – 25.

BET = B + E + T = (2 × 2) + (5 × 2) + (20 × 2) = 54

Clearly, each letter is represented by the numeral denoting its position from the end of the alphabet, i.e. Z = 1, Y = 2, ……., M = 14, …, B = 25, A = 26.

Then, SUN = S + U + N = 8 + 6 +13 = 27.

So, CAT = C + A + T = 24 + 26 + 7 = 57.

BALL = B + A + L + L = 2 + 1 + 12 + 12 = 27

In the given code, Z = 1, Y = 2, X = 3, ….., C = 24, B = 25, A = 26.
So, GO = 29 + 12 = 32 and SHE = 8 + 19 + 22 = 49.

Similarly, SOME = S + O + M + E = 8 + 12 + 14 + 22 = 56.

Taking Z = 2, Y = 3, …., N = 14, …., B = 26 and A = 27, we have
ZIP = (Z + I + P) × 6 = (2 + 19 + 12) × 6 = 198

So, VIP = (V + I + P) × 6 = (6 + 19 + 12) × 6 = 37 × 6 = 222

Clearly, each letter is coded by a numeral which is 3 less than the numeral denoting the position of the letter in the English alphabet. The code for the word is obtained by joining together physically the number codes for the individual letters.

H, E, L are 8^th, 5^th, and 12^th letters respectively. So, their codes are 5, 2 and 9 respectively. Thus, the code for Heel becomes 5229.
