Given Data

1. Letter digit codes: E = 2, M = 7, B = 6, O = 4, U = 5, R = 8.
2. Condition 1: If both the first and last letters are vowels, both are coded as '@'.
3. Condition 2: If both the first and last letters are consonants, both are coded as '#'.

Question

What is the code for the word 'EMBOU'?

Answer

@764@.

Solution

1. Check the first and last letters of 'EMBOU':
2. First letter is 'E' (vowel) and last letter is 'U' (vowel).
3. Since both first and last letters are vowels, Condition 1 applies.
4. Replace both 'E' and 'U' with '@'.
5. Substitute standard digits for the middle letters: M = 7, B = 6, O = 4.
6. Combine the coded values: '@' + 7 + 6 + 4 + '@' = '@764@'.
7. Therefore, 'EMBOU' is coded as '@764@'.
