Number Coding Decoding - Random Sequence
Number Coding Decoding - Random Sequence
NUMBER CODING DECODING : Coding with Random Sequence
This is the pattern of coding which exhibits the natural correlation of Arabic numbers with alphabetic letters. This sequence will not follow a specific pattern of assigning numbers to alphabets. The pattern can be established by various ways but in every case a set of new pattern / principle is involved which has to be done carefully.
Example 1: If FRANCE is coded 9-21-4-17-6-8, code the following words after discerning the principle/pattern involved in this example.
(1) INDIA (2) CANADA (3) GERMANY (4) NEPAL (5) PERU (6) KENYA
Solution : The pattern of assignment is read as given in the following table.
| A | B | C | D | E | F | G | H | I | J | K | L | M | N | O | P | Q | R |
| 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 | 13 | 14 | 15 | 16 | 17 | 18 | 19 | 20 | 21 |
| S | T | U | V | W | X | Y | Z | ||||||||||
| 22 | 23 | 24 | 25 | 26 | 1 | 2 | 3 |
Based on above pattern, the answers will be follows:
Example 2 : If ‘MACHINE’ is coded as 19-7-9-14-15-20-11, then how will you code ‘DANGER’ in the same code?
(a) 11-7-20-16-11-24 (b) 10-7-20-9-11-25 (c) 10-7-20-13-11-24 (d) 13-7-10-11-25
Answer : (c)
Solution : As, M = 13, A = 1, C = 3, H = 8, I = 9, N = 14 and E = 5. If we add 6 to all these numbers we get
Similarly, In DANGER , D = 4, A = 1, N = 14, G = 7, E = 5 and R = 18
Hence the answer is 10 - 7 - 20 - 13 - 11 - 24.
Example 3: If TEACH is coded 22-7-3-5-10, than the code of ROUGH will be
(a) 18-15-21-7-8 (b) 20-17-21-7-8 (c) 20-17-23-9-10 (d) 20-17-23-9-9
Answer : (c)
Solution : As , T= 20, E= 5, A= 1, C= 3, H= 8. If we add 2 to all these numbers we get
20 + 2 = 22
5 + 2 = 7
1 + 2 = 3
3 + 2 = 5
8 + 2 = 10
Similarly, in case of ROUGH, R = 18, O = 15, U = 21, G = 7, H = 8,If we add 2 to all these numbers we get
18 + 2 = 20
15 + 2 = 17
21 + 2 = 23
7 + 2 = 9
8 + 2 = 10
So, the answer is 20-17-23-9-10.
Example 4: If SWIFT is coded as 24-28-14-11-25 , than the code of DESIRE will be
(a) 9-10-24-14-11-25 (b) 9-10-24-14-23-10 (c) 9-10-17-24-9-10 (d) 9-10-25-13-23-10
Answer : (b)
Solution : As , S = 19, W = 23, I = 9,F = 6, T = 20. If we add 5 to all these numbers we get
19 + 5 = 24
23 + 5 = 28
9 + 5 = 14
6 + 5 = 11
20 + 5 = 25
Similarly, in case of DESIRE, D = 4, E = 5, S = 19, I = 9, R = 18, E = 5, If we add 5 to all these numbers we get
4 + 5 = 9
5 + 5 = 10
19 + 5 = 24
9 + 5 = 14
18 + 5 = 23
5 + 5 = 10
So, the answer is 9-10-24-14-23-10.
Example 4: If AWARE is coded as 5-27-5-22-9, than the code of YESTERDAY will be
(a) 29-9-23-24-9-22-8-5-29 (b) 29-9-23-20-9-22-8-5-29 (c) 29-9-23-24-9-25-8-5-29 (d) 29-9-21-24-9-22-8-5-29
Answer : (a)
Solution : As ,A = 1, W = 23, A = 1. R = 18, E = 5 If we add 4 to all these numbers we get
1 + 4 = 5
23 + 4 = 27
1 + 4 = 5
18 + 4 = 22
5 + 4 = 9
Similarly, in case of YESTERDAY, Y= 25,E= 5,S= 19, T= 20,E=5,R=18,D=4,A=1,Y=25, If we add 4 to all these numbers we get
25 + 4 = 29
5 +4 = 9
19 + 4 = 23
20+4 = 24
5 + 4 = 9
18 + 4 = 22
4 + 4 = 8
1 + 4 = 5
25 + 4 = 29
So, the answer is 29-9-23-24-9-22-8-5-29 .
