EPIDEMIC – FQJCDLID
Here the first three letters are made (+1), then the next three letters are made (-1), then the last two letters are made (+1).
Answer. FQJCDLID
Q.3 In a certain code language, “YEARLY” is written as “BVZIOB”. What will be the code for “ANNUAL” in the same language?
Step-by-step explanation :
Given that,
YEARLY is written as BVZIOB
Writing the numbers for the alphabets, we have
Y E A R L Y ———-> B V Z I O B
25 5 1 18 12 25 ———-> 2 22 26 9 15 2
Now, we can clearly see the relation between the numbers on both the sides. All numbers on adding are giving 27 as the answer.
Y + B = 25 + 2 = 27
E + V = 5 + 22 = 27
A + Z = 1 + 26 = 27
R + I = 18 + 9 = 27
L + O = 12 + 15 = 27
Y + B = 25 + 2 = 27
So, this is the code for the language.
Now, we have to write “ANNUAL” in the same code language.
A = 1 N = 14 N = 14 U = 21 A = 1 L = 12
First alphabet = 27 – A = 27 – 1 = 26 = Z
Second alphabet = 27 – N = 27 – 14 = 13 = M
Third alphabet = 27 – N = 27 – 14 = 13 = M
Fourth alphabet = 27 – U = 27 – 21 = 6 = F
Fifth alphabet = 27 – A = 27 – 1 = 26 = Z
Sixth alphabet = 27 – L = 27 – 12 = 15 = O
A N N U A L —————> Z M M F Z O
Hence, “ANNUAL” is written as “ZMMFZO” in the same code language.
Answer. ZMMFZO
Q.4 In a certain code language “CONSTRUCTION” is written as “EMPQVPWAVGQL”. What will be the code for “DESTRUCTION” in the same language?
Step-by-step explanation :
Given that,
YEARLY is written as BVZIOB
Writing the numbers for the alphabets, we have
C O N S T R U C T I O N ———-> E M P Q V P W A V G Q L
3 15 14 19 20 18 21 3 20 9 15 14 ———-> 5 13 16 17 22 16 23 1 22 7 17 12
Now, we can clearly see the relationship between the numbers on both sides. First 2 are added then 2 are subtracted.
C(+2) O(-2) N(+2) S(-2) T(+2) R(-2) U(+2) C(-2) T(+2) I(-2) O(+2) N(-2)
E M P Q V P W A V G Q L
D(+2) E(-2) S(+2) T(-2) R(+2) U(-2) C(+2) T(-2) I(+2) O(-2) N(+2)
F C U R T S E R K M P

Number Based Questions and Answers
Q.1 In a certain code language ‘1 2 3 4 5 6 7 8 9 10’ is written as COMPUTRSNE, then how will 4 3 2 1 6 5 10 9 8 7 be written in that code language?
Solution :-
1 2 3 4 5 6 7 8 9 10
C O M P U T R S N E
So,
4 3 2 1 6 5 10 9 8 7
P M O C T U E N S R
Answer. P M O C T U E N S R
Q.2 In a certain code language “EASY” is written as “5117”. In the same code language, how will “BEAM” be written as?
Solution :
EASY →
E is the 5th alphabet in the series
A is the first alphabet in the series
S is the 19th alphabet, which makes it (1 + 9 = 10 ⇒ 1 + 0 = 1)
Y is the 25th alphabet, which makes it (2 + 5 = 7)
Hence, EASY = 5117
Similarly,
BEAM →
B is the 2nd alphabet in the series
E is the 5th alphabet in the series
A is the 1st alphabet in the series
M is the 13th alphabet, which makes it (1 + 3 = 4)
Hence BEAM = 2514
Answer. 2514
Q.3 “SPECIAL” is written as “65” in a certain code language what will “CONNECT” be coded as?
Solution :
SPECIAL → Sum of the place value of each alphabet in the alphabetical order
SPECIAL = 19 + 16 + 5 + 3 + 9 + 1 + 12 = 65
So, CONNECT = 3 + 15 + 14 + 14 + 5 + 3 + 20 = 74
Answer : 74
Q.4 In a certain code language, “ISSUE” is written as “341145”, in the same code language what will
be the code for “DATES”?
Solution :
ISSUE → Multiplying the place value of each alphabet in the alphabetical series
ISSUE = 9 × 19 × 19 × 21 × 5 = 341145
Similarly, DATES = 4 × 1 × 20 × 5 × 19 = 7600
Answer : 7600
