Number Coding Decoding - Backward Sequence
Number Coding Decoding - Backward Sequence
NUMBER CODING DECODING: Coding with Backward Sequence
This is the pattern of coding which exhibits the natural correlation of Arabic numbers with alphabetic letters. For instance, alphabets A to Z are assigned the numeric codes from 1 to 26 in the reverse order like A = 26, B = 25 and so on.
NOTE : Backward order position of a letter = 27 − Forward order position of letter
For Example : Backward order position of B = 27 − Forward order position of B = 27 − 2 = 25
Example 1 : If GREAT is coded as 20 - 9 -22 - 26 - 7, then how will you code the following :
(a) FATE (b) DATE (c) MATE (d) RATE
Solution : In this question , if we assign numbers to these alphabets in the reverse order we get : A = 26 , B = 25, C = 24 ... and so on. Similarly,
Example 2 : If BAG = 71, then VICE = ?
(a) 69 (b) 70 (c) 75 (d) 90
Answer : (a)
Solution : According to the backward or reverse sequence of alphabets, B = 25 , A = 26 and G = 20. If we add all these numbers we get = 25 + 26 + 20 = 71. Similarly, V = 5 , I = 18 , C= 24 and E = 22. If we add these numbers = 5 + 18 + 24 + 22 = 69 (using backward letter positions). Hence the answer is 69.
Example 3 : If READ is coded as 9-22-26-23, then DREAM =?
(a) 23-9-22-26-14 (b) 23-8-22-26-14 (c) 23-9-21-25-14 (d) 23-9-22-24-14
Answer : (a)
Solution : In this question , if we assign numbers to these alphabets in the reverse order we get : A = 26 , B = 25, C = 24 ... and so on.
Similarly,
In case of DREAM,
D=23
R=9
E=22
A=26
M=14
So, the answer is 23-9-22-26-14.
Example 4 : If GO is coded as 19-11 ,SHE is coded as 7-18-21, then SOME =?
(a) 7-11-12-20 (b) 7-11-13-21 (c) 7-10-13-21 (d) 7-10-12-21
Answer : (b)
Solution : In this question , if we assign numbers to these alphabets in the reverse order we get : A = 26 , B = 25, C = 24 ... and so on.
In case of GO,
G=20, subtract 1 from 20, 20-1= 19
O=12, subtract 1 from 12, 12-1 =11
Similarly, in case of SHE,
S= 8, subtract 1 from 8, 8-1= 7
H= 19, subtract 1 from 19, 19-1= 18
E= 22,subtract 1 from 22, 22-1 = 21
Noe , in case of SOME,
S= 8, subtract 1 from 8, 8-1=7
O =12, subtract 1 from 12, 12-1 =11
M= 14, subtract 1 from 14, 14-1= 13
E= 22,subtract 1 from 22, 22-1 = 21
So, the answer is 7-11-13-21.
Example 5 : If TO is coded as 5-10, then THE =?
(a) 7-19-22 (b) 6-19-22 (c) 5-17-20 (d) 4-17-20
Answer : (c)
In this question , if we assign numbers to these alphabets in the reverse order we get : A = 26 , B = 25, C = 24 ... and so on.
In case of TO,
T=7, subtract 2 from 7, 7-2= 5
O=12, subtract 2 from 12, 10-2 = 8
Similarly, in case of THE,
T=7, subtract 2 from 7, 7-2= 5
H= 19, subtract 2 from 19, 19-2 = 17
E= 22, subtract 2 from 22, 22-2 = 20
So, the answer is 5-17-20.
