Type 7 Symbol Coding & Decoding Practice Questions Answers Test With Solutions & More Shortcuts

Answer: (b)

Let A = 1, B = 2, C = 3, ……, X = 24, Y = 25, Z = 26.

Then, M = 13 = 1 + 3 = 4; O = 15 = 1 + 5 = 6; B = 2; I = 9;

L = 12 = 1 + 2 = 3; T = 20 = 2 + 0 = 2; Y = 25 = 2 + 5 = 7.

So, MOBILITY = 46293927.

Similarly, X = 24 = 2 + 4 = 6; N = 14 = 1 + 4 = 5.

So, EXAMINATION = 56149512965.

Answer: (e)

Clearly, vowels A, E, I, O, U are coded as 1, 2, 3, 4, 5 respectively.

Each of the consonants in the word is moved one step forward to give the corresponding letter of the code.

So, the code for ACID becomes ID3E.

Answer: (c)

Clearly, each word is coded by the numeral which is 1 less than the number of letters in the word. Since there are 10 letters in the word GOVERNMENT,

so required code = 10 - 1 = 9.

Answer: (b)

Putting  A = 1, B = 2, C = 3, ……, X = 24, Y = 25, Z = 26,

we have: ZEBRA > Z/E/B/R/A > 26/5/2/18/1 > 2652181.

COBRA > C/O/B/R/A > 3/15/2/18/1 > 3152181.

Answer: (d)

H, $, M, and E are codes for 3, 8, 4, and 5 respectively.

Y at the first place and # at the last place indicate that the number should begin and end with an odd digit.

Clearly, only (B) and (C) satisfy this condition.
