In a certain code language, GOURD is written as 21-4-5-10-24. How wil…

1   2    3    4   5    6   7     8    9  10  11  12  13

 A   B   C    D   E    F   G    H    I    J    K    L   M

 ↓    ↓    ↓    ↓    ↓     ↓   ↓    ↓     ↓   ↓    ↓    ↓    ↓

 Z   Y    X   W   V    U   T    S    R   Q   P    O   N

26  25  24  23  22  21  20  19  18  17  16  15  14

 

The pattern here is;

(Vowels are coded as A  1,  E  2,  I  3,  O  4,  U  5)

(for Consonants, the opposite value is used and it is added by 1)

So,

G (20th position from reverse) 20+1= 21

O  4 (Vowel)

U  5 (Vowel)

R  (9th position from reverse) 9+1= 10

D (23rd position from reverse) 23+1= 24

Similarly,

B (25th position from reverse) 25+1= 26

R (9th position from reverse) 9+1= 10

I   3 (Vowel)

N  (13th position from reverse) 13+1= 14

J  (17th position from reverse) 17+1= 18

A  1 (Vowel)

L  (15th position from reverse) 15+1= 16

Thus, 26-10-3-14-18-1-16 is correct.
