"Under this pattern, letters numbers are given and their codes are given right under them. Candidates are required to find the code for a particular letter/group/word/number according to the given conditions". Also learn all types of coding decoding topics in verbal reasoning section.

Some example questions with solved solutions for Conditional Coding & Decoding:

In the question below, is given a group of numbers followed by four combinations of letters/symbols. You have to find out which of the combinations correctly represents the group of numbers based on the following coding system and the conditions that follow and mark your answer accordingly.

Conditions
(i) If a number begins and ends with a non-zero odd digit, then the first and the last digits are to be coded as Y and #, respectively.
(ii) If a number begins and ends with an even digit (including zero), then the first and the last digits are to be coded as B and X, respectively.

What will be the code for '764981'?

1. A % M L $ @
2. Y % M L $ @
3. Y % M L $ @
4. A % M L $ #

When condition is not applied, the coding is done as follows, But here the number begins and ends with a non-zero odd digit and therefore condition(i) is applied here. As condition(i) is applied here 7 and 1 will be coded as Y and #, respectively ∴ Code for 764981 = Y%ML$#.

In the question below, is given a group of letters followed by four combinations of digits/symbols. You have to find out which of the combinations correctly represents the group of letters based on the following coding system and the conditions that follow and mark your answer accordingly.

Conditions
(i) If both first and last letters are vowels, their codes are to be interchanged.
(ii) If the first letter is a consonant and the last letter is a vowel, both are to be coded as the code for the vowel.
(iii) If the first letter is a vowel and the last letter is a consonant, both are to be coded as the code for the consonant.

Find the code for 'IBHJRE'.

1. #614@5
2. 5164@%
3. %164@#
4. #164@5

When condition is not applied, the coding is done as follows. But here the 1st letter (I) and the letter (E) are vowels and therefore condition (i) is applied here then, I and E will interchange their codes.

∴ Code for IBHJRE = #164@5.

What will be the code for 36250098?

1. $RFLTTG€
2. #RFLTTG@
3. #RFLTTG€
4. $RFLTTG@
5. None of these

When condition is not applied, the coding is done as follows, But here the first digit is odd and the last digit is even, therefore condition (ii) is applied here, As condition (ii) is applied here, 3 is coded as # and 8 is coded as € ∴ Code for 36250098 = #RFLTTG€

QLP↓RNT is the code for the following numbers?

1. 6580470
2. 4780650
3. 6580470
4. Data inadequate
5. None of these

Q, L, P, ↓, R, N, and T are the codes for 4, 5, 8, 0, 6, 7 and 0 respectively. So, the required number is 4580670.

$QRL↑H@ could be the code for which of the following numbers?

1. 8465032
2. 8456037
3. 8465034
4. 6475031
5. None of these

Q, R, L, H are the codes for 4, 6, 5, 3 respectively. ↑ is the code for 0.

So, $QRL↑H@ shall be the code of a number of the form ?46503?, in which the first digit must be even and the last digit must be odd. Clearly, there is no such number in the given alternatives.

What will be the code for 'ARFTHE'?

1. %358#%
2. 4358#%
3. 4358#4
4. %385#%

From Statement III,
If both the first and last letter are vowels, the both are coded as the last letter

What will be the code for 'NFRSCA'?

1. 753%20
2. 053%24
3. 0230%0
4. 053%20
