In a certain code language, ‘CARD’ is coded as ‘4628’ and ‘NEAT’ is coded as ‘3574’. What is the code for ‘A’ in that language?2078

The correct option is 4.

To find the code for the letter ‘A’, let us compare the given word-code pairs:

1. ‘CARD’ is coded as ‘4628’

2. ‘NEAT’ is coded as ‘3574’

Let us identify the common letter present in both words:

In both ‘CARD’ and ‘NEAT’, the common letter is ‘A’.

Now, let us examine the numbers in both codes to find the common digit:

In ‘4628’ and ‘3574’, the common digit is ‘4’.

Since ‘A’ is the only letter shared between the two words, and ‘4’ is the only digit shared between the two codes, the code for ‘A’ must be 4.
