Coding Decoding Quiz 16

Direction : Study the following question carefully and choose the right answer.
1
If in a certain code BAT = 23 and CAT = 24, then how will you  code HEN = ?
» Explain it
D
C is one step ahead of B and code for CAT is 1 more than that for BAT. Thus the later are coded by numeral denoting their positions in the English alphabet.

i.e. A = 1, B = 2, C = 3 ………,  Y = 25, Z = 26.

So, HEN ⇒ H + E + N = 8 + 5 + 14 = 27.
2
If A = 26, SUN = 27, Then MOON = ?
» Explain it
B
Here, each letter is represented by numeral denoting its position from the end of the English alphabet.

i.e. Z = 1, Y = 2, ……..M = 14,….., C = 24, B = 25, A = 26.

Then SUN = 8 + 6 + 13 = 27

MOON = 14 + 12 + 12 + 13 = 51.
3
If A = 2, M = 26, Z = 52, then RAT = ?
» Explain it
C
Clearly, each letter is assigned a numerical value which is twice the numeral denoting its positing in English alphabet.

So RAT = R + A + T

              = 18 × 2 + 2 + 20 × 2

              = 36 + 2 + 40 = 78.
4
In a certain code, the word DEAL is coded 4 – 5 – 1 – 12 following the same rule of coding, what should be the code of the word GENTS?
» Explain it
A
Each letter is coded by the numerical denoting its position in the English alphabet. Thus, A is coded as 1, B as 2, C as 3,….. M as 13, N as 14..... Y as 25, Z as 26.

So, the code for GENTS is

G – E – N – T – S        =        7 – 5 – 14 – 20 – 19.

5
In certain code DEAF is written as 3587 and FILE is written as 7465. How is IDEAL written in that code?
» Explain it
B
  Letter   D   E   A   F   I   L
  Code   3   5   8   7   4   6

The, Code for IDEAL is 43586.
