it toor' is coded as 46 and 'blower' is coded as 57 then how is tower' coded?
Answers
Answer:Coding is a system of signals. This is a method of transmitting information in
the form of codes or signals without it being known by a third person.
The person who transmits the code or signal, is called the sender and the
person who receives it, is called the receiver. Transmitted codes or signals are
decoded on the other side by the receiver—this is known as decoding.
In questions on coding-decoding, a word (basic word) is coded in a
particular way and the candidates are asked to code other word in the same
way. The coding and decoding tests are set up to judge the candidate’s ability
to decipher the rule that has been followed to code a particular word/message
and break the code to decipher the message.

Here, are some methods/techniques are given below to remember the
positions of English alphabets in forward or backward order.

1. By using EJOTY and CFILORUX formulae, we can easily remember the position of
letters of English alphabets.

● Backward order position of a letter = − 27 Forward order position of letter
e.g., Backward order position of B = 27 − Forward order position of B = − = 27 2 25
Illustration 1. If CUP = 40, then KITE = ?
(a) 10 (b) 20 (c) 30 (d) 45
Solution (d) As, C

Illustration 2. What is the number place of G
from right side?
(a) 10 (b) 20
(c) 25 (d) 30
Solution (b) 27 − G = − 27 7 (from left)
= 20
2. By using V Q L G B and X U R O L I F C, we can easily remember the position of
letters of alphabet in reverse order.
