In a certain code language "READER" is written as "123421" and "DIRTY" is written as "49178". How will "DEARER" be written in that code language?
- A432121
- B423212
- C423121
- D412312
Solution & Step-by-step Explanation
This is a direct substitution code where each letter corresponds to a specific number as shown below:
From READER → 123421:
R = 1
E = 2
A = 3
D = 4
From DIRTY → 49178:
D = 4
I = 9
R = 1
T = 7
Y = 8
Now, let's substitute the matching code values for the word DEARER:
D = 4
E = 2
A = 3
R = 1
E = 2
R = 1
Putting it together: 423121.
