Coding Decoding
Directions (5-7):Â Following is given a set of letter/digits and the corresponding letter code of each digit followed by certain conditions for coding.
In each question below are given a group of letters/digits followed by four combinations of digits/symbols, Numbered (a), (b), (c), (d). 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 the number of those combinations as your answer. If none of the combinations correctly represents the group of letters, mark e) i.e. „None of these‟, as your answer.
a)If the first letter is consonant and the fourth digit is odd, both are to be coded as the code for that consonant.
b)If the last letter is a vowel and the second digit is divisible by 2, both are to be coded as the code for the first element.
5) What is the code for ‘M8XPCI’?
a) !^®@&!
b) !! ®@&!
c) !^®@&*

c) One
d) More than Three
e) None
Answers :
Directions (1–4):
In the given Machine Input the following pattern is followed:
Step I: The smallest number is arranged in the first position in the left end in the sequence.
Step II: The highest number is pushed to the last position in the right end in the sequence.
Similarly, lowest numbers are arranged from left to right side in the left end and the highest from right to left side in the right end.
Final position is all the numbers are arranged in ascending order from left to right.
1) Answer: e
2) Answer: a
3) Answer: d
4) Answer: d
Directions (5-7) :
5) Answer: b
The last letter is a vowel and 2nd digit is divisible by 2. Hence it follows condition (ii).
So, both are to be coded as the code for first element.
Thus ‘M8XPCI’ is represented as ‘!!®@&!’
6) Answer: d
The first letter is a consonant and 4th number is odd.
Hence it follows condition (i).
So, both are to be coded as the code for that consonant.
Thus, ‘Q4E75C’ is represented as ‘µΩ%µ©&’
7) Answer: d
The last letter is a vowel and 2nd digit is divisible by 2. Hence it follows condition (ii).
So, both are to be coded as the code for first element.
Thus ‘G8IMXU’ is represented as ‘$$>!®$’
Directions (8-10) :
8) Answer: a
9 7 6 9 7 2 4 5 9 2 ​​7 ​2 4 6 9 7 8 6 5 3 7 8 9 7 6 5 3 4 2 8 ​4 7 8 4 5 6
Clearly, 6 and 5 have appeared three times together in the given number series.
Thus, the correct answer is Three.
9) Answer: c
Clearly, 5 appears four times in the given number series.
9 7 6 9 7 2 4 5 9 2 ​​7 ​2 4 6 9 7 8 6 5 3 7 8 9 7 6 5 3 4 2 8 ​4 7 8 4 5 6
Thus, the correct answer is Four.
10) Answer: e
Clearly, there are no 9s that are there preceded by 6 but not followed by 7.
9 7 6 9 7 2 4 5 9 2 ​​7 2 4 6 9 7 8 6 5 3 7 8 9 7 6 5 3 4 2 8 4 7 8 4 5 6
Thus, the correct answer is none.
