Question

Answer

Clearly, the order of letters in the word is reversed and then each letters is replaced by the numeral denoting its position in the English alphabet. Next, 2 is added to each numeral and the numerals so obtained are joined together physically to get the code. Thus, we have :

RED → DER → 4/5/18 → 6/7/20 → 6720.

GREEN → NEERG → 14/5/5/18/7 → 16/7/7/20/9 → 1677209.
Hence, option B is correct.

RED → DER → 4/5/18 → 6/7/20 → 6720.

GREEN → NEERG → 14/5/5/18/7 → 16/7/7/20/9 → 1677209.
Hence, option B is correct.

Answer

Explanation:

Decoding RED to 6720:
- The word RED has 3 letters, so each letter is represented by 4 digits.
- R is the 18th letter of the alphabet, so it is represented by 18 in the code.
- E is the 5th letter of the alphabet, so it is represented by 05 in the code.
- D is the 4th letter of the alphabet, so it is represented by 04 in the code.
- Combining these, we get the code for RED as 180504.

Decoding GREEN:
- GREEN has 5 letters, so each letter is represented by 4 digits.
- G is the 7th letter of the alphabet, so it is represented by 07 in the code.
- R is the 18th letter of the alphabet, so it is represented by 18 in the code.
- E is the 5th letter of the alphabet, so it is represented by 05 in the code.
- E is the 5th letter of the alphabet, so it is represented by 05 in the code.
- N is the 14th letter of the alphabet, so it is represented by 14 in the code.
- Combining these, we get the code for GREEN as 07180514, which is represented as 1677209.

Therefore, the correct answer is option B - 1677209.

Answer

Here,
R comes 18th in alphabetical order
E comes 5th in alphabetical order
D comes 4th in alphabetical order

R=18+2=20
E=5+2=7
D=4+2=6

R/E/D in reverse order= D/E/R=6720

.•. Therefore, DER=RED=6720

NOW, GREEN;

G/R/E/E/N= 9207716

.•. Therefore, NEERG=GREEN=677209

SO, OPTION B IS THE ANSWER 1677209

Answer

1677209
