Test Level 2: Coding Decoding - Question 1

How will 'Incredible' be coded as according to this code language?

Detailed Solution for Test Level 2: Coding Decoding - Question 1

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.

Test Level 2: Coding Decoding - Question 10

Find the resultant of the second row, if N is the resultant of the first row.

Detailed Solution for Test Level 2: Coding Decoding - Question 10

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)

Test Level 2: Coding Decoding - Question 11

Find the resultant of the first row if N is the resultant of the second row.

Detailed Solution for Test Level 2: Coding Decoding - Question 11

109 − 56 = 53 (As per step 1)
53 + 39 = 92 (As per step 5)
N = 92
216 - 92 = 124 (As per step 3)
124 × 09 = 1116 (As per step 2)

Test Level 2: Coding Decoding - Question 12

N is the resultant of the first row. Find the difference if N is subtracted from the resultant of second row.

Detailed Solution for Test Level 2: Coding Decoding - Question 12

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

Test Level 2: Coding Decoding - Question 13

Using the given rules, find the code for 'student perfect'.

Detailed Solution for Test Level 2: Coding Decoding - Question 13

 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.

Test Level 2: Coding Decoding - Question 14

What will be the code for 'am' in this code language?

Detailed Solution for Test Level 2: Coding Decoding - Question 14

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.
Following the same rules, code for 'am' will be 26#n.

Test Level 2: Coding Decoding - Question 15

What does the code 12@m 26@b 9@h represent?
