Q. How will 'Incredible' be coded as according to this code language?
Explanation
Each given code comprises three different elements – a number, a symbol and a letter; where-
(1) The number is the reverse numeric value for the first letter of the word.
(2) For the second element, a unique symbol is chosen for the last letter of the word. To exemplify, the word 'All' has L as its last letter; and therefore, for L, ! is its second element in the code.
(3) The last element comprises the letter which is third to the right(in English Alphabet) of the last letter of the word. For example, in the word 'All', L is the last letter; so third to the right of L is O.
As per this logic, the words and their specific codes are as given below:
Following the logic, the code for 'Incredible' will be 18#H.

Question for Practice Questions Level 2: Coding & Decoding
Try yourself:Directions: In this question, two rows are given and to find out the resultant of a particular row, you need to follow the steps given below. Give answer to the question asked accordingly. The operations on numbers progress from left to right.
Step 1: If an odd number is followed by an even number, then the second number is to be subtracted from the first number.
Step 2: If an even number is followed by a composite odd number, then they are to be multiplied.
Step 3: If an even number is followed by a number which is a perfect Cube, then the even number is to be subtracted from perfect cube.
Step 4: If an even number is followed by a prime odd number, then the first number is to be divided by the second number.
Step 5: If an odd number is followed by another composite (a non-prime number) odd number, then they are to be added.
Q. Find the resultant of the second row, if N is the resultant of the first row.
Explanation
12 × 09 = 108 (As per step 2)
125 − 108 = 17 (As per step 3)
N = 17
17 + 21 = 38 (As per step 5)
38 × 15 = 570 (As per step 2)

Q. N is the resultant of the first row. Find the difference if N is subtracted from the resultant of second row.
Explanation
182 ÷ 13 = 14 (As per step 4)
14 − 9 = 5 (As per step 5)
N = 5
50 ÷ 5 = 10 (As per step 4)
10 + 24 = 34 (As per step 1)
Hence, 34 - 5 = 29

'chairs doors blue right' is coded as 19@g 6#v 9#h 9@h.
Q. Using the given rules, find the code for 'student perfect'.
Explanation
If the number of letters in a word is odd, then symbol is @.
If the number of letters in a word is even, then symbol is #.
E.g. Number of letters in word 'play' is 4, so the symbol will be #.
The letter in the code is opposite to the last letter of the word in the alphabet in terms of position.
E.g. Last letter in the word 'play' is y. So, the letter in code will be b, as it is opposite to y.
The number in the code is the position of the letter opposite to the second-last letter of the word.
E.g. 'a' is the second-last letter in the word 'play'.
Opposite to a is z, and the position of z in alphabet is 26. So, the number will be 26.
Hence, the code for 'play' will be 26#b.
Now, code for 'student' will be 13@g.
Similarly, code for 'perfect' will be 24@g.
