EXERCISE
1. In a certain code language, ‘GIVE’ is written as ‘VIEG’ and ‘OVER’ is written as ‘EVRO’. How will ‘DISK’ be written in that same code?
A: SIKD
Solution:
2. In a coding, system, APPLE is represented as ZKKOV. In such system, COW will be represented as
A: XLD
Solution: 
3. If CUP = 40, then KITE = ?
A: 45
Solution:
As,
3 21 16
C U P 
3 + 21 + 16 = 40
Similarly,
11 9 10 5
K I T E 
11 + 9 + 20 + 5 = 45
(using forward letter positions)
4. If BAG = 71, then VICE = ?
A: 69
Solution:
As,
25 26 20
B A G 
25 + 26 + 20 = 71
Similarly,
5 18 24 22
V I C E 
5 + 18 + 24 + 22 = 69
(using backward letter positions)
Study the following letters and their corresponding digits codes following by certain conditions of coding and then answer the questions given below them by finding out which of the digits combinations given in (a), (b), (c) and (d) is the coded form of the letters-groups given in each question and mark your answer accordingly.
Conditions :
(i) If both the first and the last letters in the group are vowels, both should be coded as $.
(ii) If both the first and the last letters in the group are consonants, both should be coded as #.
5. KUNAJB
A: #0391#
Solution:
We know that, in English alphabets A, E, I, O, U letters are vowels and remaining letters are consonants.
From condition (ii),
