Coding-Decoding is a reasoning process where letters, numbers, or symbols are transformed using specific rules, and the task is to identify the pattern to encode/decode given information.

Coding-Decoding questions and answers are provided below for you to learn and practice.

Question 1: If EARTH is written as FCUXM in a certain code. How is MOON written in that code? 

Solution: 

Question 2: If DELHI is written as EDMGJ in a certain code. How is NEPAL written in that code?

Solution :  

Question 3: If SYMBOL is written as NZTMPC is it a certain code? How is NUMBER written in that code? 

Solution

Acc. to question 
 


Question 4: In a certain code, COMPUTER is written as PMOCRETU, how is DECIPHER written in that code? 

Solution

Acc. to question 
 


Question 5: In a certain code, NEWYORK is written as 111, how is NEWJERSEY written in that code?

Solution

In NEWYORK 
N = 14, E = 5, W = 23, Y = 25, O = 15, R = 18, K = 11 
Total = 14 + 5 + 23 + 25 + 15 + 18 + 11 = 111 
In NEWJERSEY 
Total = 14 + 5 + 23 + 10 + 5 + 18 + 19 + 5 + 25 
= 124 
 

Question 6: In a certain code, HARYANA is written as 8197151, how is DELHI written in that code? 

Solution

We used the number of alphabets here. 
H = 8 
A = 1 
R = 18 = 1+8 = 9 
Y = 25 = 2+5 = 7 
For DELHI 
D = 4 
E = 5 
L = 12 = 1+2 = 3 
H = 8 
I = 9 
Hence, DELHI is written as 45389. 

Question 7: In a certain code BOMB is written as 5745 and BAY is written as 529, how is BOMBAY written in that code?

Solution

Acc. to question 
Use the numbers to relate the words 

      B O M B      B A Y      ->          B O M B A Y 
      5 7 4 5      5 2 9                  5 7 4 5 2 9

Question 8: COMPUTER" is coded as 3 15 13 16 21 20 5 18, and "DEVICE" is coded as 4 5 22 9 3 5. Then, what would be the code for "RECIPE"?

Solution

In this case, we can see that each letter is written as its position in the alphabet:

R is the 18th letter, so it is written as 18.
E is the 5th letter, so it is written as 5.
C is the 3rd letter, so it is written as 3.
I is the 9th letter, so it is written as 9.
P is the 16th letter, so it is written as 16.
E is the 5th letter again, so it is written as 5.

Thus, "RECIPE" is written as 18 5 3 9 16 5.

Question 9: "HELLO" is coded as 8 5 12 12 15, and "WORLD" is coded as 23 15 18 12 4. Then, what would be the code for "GREAT"?

Solution

In this case, we can see that each letter is written as its position in the alphabet:

G is the 7th letter, so it is written as 7.
R is the 18th letter, so it is written as 18.
E is the 5th letter, so it is written as 5.
A is the 1st letter, so it is written as 1.
T is the 20th letter, so it is written as 20.

Thus, "GREAT" is written as 7 18 5 1 20.

Question 10: "APPLE" is coded as 1 16 16 12 5, and "BANANA" is coded as 2 1 14 1 14 1. Then, what would be the code for "GRAPE"?

Solution

In this case, we can see that each letter is written as its position in the alphabet:

G is the 7th letter, so it is written as 7.
R is the 18th letter, so it is written as 18.
A is the 1st letter, so it is written as 1.
P is the 16th letter, so it is written as 16.
E is the 5th letter, so it is written as 5.

Thus, "GRAPE" is written as 7 18 1 16 5.
