What is the code for the word 'COSTARICA'?

The logic follows here is:

In the word COSTARICA,

The first letter is a consonant (C) and the last letter is a vowel (A), therefore both these letters are coded as '&'

The fifth letter is a vowel and the third letter is a consonant, therefore both these letters are coded as 'K'

Now, Check each option one by one

1) # $ K @ K * + # =

Here, the First and Last letter is not '&', therefore Option 1) is incorrect.

2) & $ K @ K * # = &

Here, the first and last letter is '&' and the fifth and third letter is 'K'.

also, there are separate symbols used for the remaining letters, therefore Option 2) is correct.

3) & $ K # K = + # &

Here, the first and last letter is '&' and the fifth and third letter is 'K'.

In this option, the code for 'T' and 'C' is the same i.e. '#', therefore, Option 3) is incorrect.

4) & $ > @ = * + # &

Here, the first and last letter is '&' but the fifth and third letter is not 'K', therefore Option 4) is incorrect.

Hence, the correct answer is Option 2).
