Question 1
Ans: 39
Working from top to bottom, double each number
and subtract 1, then 2, then 3 etc.
Question 2
• Can you discover the missing number
in this series?
37, 10, 82
29, 11, 47
96, 15, 87
42, ?, 15
Ans: 6.
The number in the middle of each triple is the same
as the digits of either end's number when added
together. 3+7=10=8+2 and so on
Question 3
Identify the next two numbers in this
series?
101, 112, 131, 415, 161, 718, ???, ???
Ans: 192 021
If you look at it as two-digit numbers you'll see:10 11
12 13 14 15 16 17 18 19 20 21
Question 4
Fill in the question mark place with an
option
Ans: Option C
All four segments use the same figures: two squares, one
circle, and one triangle. In the first segment, the squares
are on the outside of the circle and triangle. In the second
segment, the squares are below the other two. In the third
segment, the squares on are the inside. In the fourth
segment, the squares are above the triangle and circle.

Question 7
• WHICH NUMBER COMES NEXT
IN THE SERIES?
2, 6, 12, 20, 30, 42, 56, _______
Ans:72
(1)(2) = 2;
(2)(3) = 6;
(3)(4) = 12;
(4)(5) = 20;
(5)(6) = 30;
(6)(7) = 42;
(7)(8) = 56;
(8)(9) = 72;
Question 8
WHICH NUMBER COMES NEXT
IN THE SERIES ?
1, 2, 10, 37, 101, _______
Ans:: 226
2 - 1 = 1; 10 - 2 = 8; 37 - 10 = 27; 101 - 37 = 64;
The differences between two consecutive numbers
are 1, 8, 27, 64. (cubes of integers starting with 1).
So, 101 + 53 = 101 + 125 = 226

Caesar Cipher
• It is a Substitution Cipher that involves replacing
each letter of the secret message with a
different letter of the alphabet which is a fixed
number of positions further in the alphabet.
Example
In this example, each letter in the plaintext message
has been shifted 3 letters down in the alphabet.
Plaintext: This is a secret message
Ciphertext: wklv lv d vhfuhw phvvdjh
Caesar Cipher
Decipher:
Mx mw rsx tpeywmfpi
No. of shifts: 4
Ans:It is not plausible
Atbash Cipher
• The Atbash cipher is a very specific case of a
substitution cipher where the letters of the
alphabet are reversed. In otherwords, all As are
replaced with Zs, all Bs are replaced with Ys,
and so on.
• Because reversing the alphabet twice will get
you actual alphabet, you can encipher and
decipher a message using the exact same
algorithm.

Ans: Are You Right
Pigpen Cipher
The pigpen cipher is a simple substitution cipher
exchanging letters for symbols based on a grid.

Tap Code
Each letter was communicated by
tapping two numbers. The first
designated the horizontal row and
the second designated the vertical
row. The letter "X" was used to
break up sentences and the letter
"C" replaced the letter "K".
For "WATER" the code would be
the following

Rail Fence Cipher
•
In the rail fence cipher, the plaintext is written downwards
on successive "rails" of an imaginary fence, starting a new
column when the bottom is reached. The message is then
read off in rows. For example, if we have 3 rails and a
message of "This is a secret message", you would write
out:
TSACTSG
HISRMSE
I SEEEAJ
•
•
The last J is just a random letter to fill in the space. The
secret message is then condensed and regrouped.

Morse Code
•
Morse code is a method for transmitting information, using
standardized sequences of short and long marks or pulses commonly known as "dots" and "dashes" - for the letters,
numerals, punctuation and special characters of a message.
Example:
‘Winners’ is encoded as
follows:
.-- .. -. -. . .-. ...
Morse Code
Decode:
... - .- -.-- .... ..- -. --. .-. -.-- .-.... -.-- ..-. --- --- .-.. .. ... ....
Ans: stay

Anagram
This is the anagram of a famous
quote:

Ans: Time and tide wait for no man
Face-Off
Rules
1) Each team will have 5 mins to encrypt MESSAGE of their choice using
CAESAR CIPHER
2) The message encrypted should be legible and meaningful. Which means
it can’t be random words. The message must be a sentence or phrase.
3) The team to correctly decipher the code first wins.
4) If wrongly decoded the team loses.
5) The No. of shifts should be from 1-5.
6) The encoding team will not inform the opposite team about the number
of shifts.
7) But the judges will be told before the encryption begins
Caesar Cipher
• It is a Substitution Cipher that involves replacing
each letter of the secret message with a
different letter of the alphabet which is a fixed
number of positions further in the alphabet.
Example
In this example, each letter in the plaintext message
has been shifted 3 letters down in the alphabet.
