type 7 symbol coding & decoding Detailed Explanation And More Example

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: (c)

As, H → @ E → 8 A → 5 R → 3 T → 1 and F → # E → 8 A → 5 S → 4 T → 1

Similarly, F → # A → 5 R → 3 T → 1 H → @ E → 8 S → 4 T → 1

Therefore, FARTHEST ⇒ #531@841

Answer: (d)

As, G → 5 O → @ N → ©  E → 9 and S → 6 E → 9 A → % L → *

Similarly, L → * O → @ G → 5 S → 6 LOGS ⇒ * @ 56

Answer: (d)

As, D → 5 O → @ W → 9 N → # and N → # A → 6 M → % E → 3

Similarly, M → % O → @ D → 5 E → 3

Therefore, MODE ⇒ % @ 53
