Coding – Decoding (SSC CGL 2019 Tier -1)

1. If each letter of the English alphabet is assigned an odd numerical value in increasing order, such as A = 1, B = 3 and so on, then what will be the code of 'HONEY'? [S.S.C CGL 05/03/2020 (Morning)]

(a) 132725745
(b) 132725747
(c) 152927949
(d) 152927947

Correct Answer: (c) 152927949

Solution:According to the question :

If the positional value of a letter is "n", then the code of the letter will be "2n - 1".

H = 15, O = 29, N = 27, E = 9 and Y = 49

Therefore, the code for 'HONEY' is '152927949'

Hence, '152927949' is correct answer.

2. In a certain code language, 'CAUGHT' is coded as '326212087'. How will 'SOLDER' be coded as in that language? [S.S.C CGL 05/03/2020 (Afternoon)]

(a) 1812122459217
(b) 1915124359218
(c) 2012152358206
(d) 1912122359

Correct Answer: (d) 1912122359

Solution:The logic followed here is,

For C, U and H → Positional values of small letter → C = 3, U = 21 & H = 8

For A, G and T → Positional values of opposite letter → A = 26, G = 20 & T = 7

Therefore, CAUGHT → 326212087

Similarly,

For S, L & E → Positional value of same letter → S = 19, L = 12 & E = 5

For O, D & R → Positional value of opposite letter → O = 12, D = 23 & R = 9

Therefore, SOLDER → 1912122359

Hence, 1912122359 is the correct answer.

3. In a certain language, 'PAGE' is coded as '161495'. How will 'PART' be coded as in that language? [S.S.C CGL 06/03/2020 (Morning)]

(a) 16128620
(b) 16132420
(c) 16125020
(d) 16136220

Correct Answer: (b) 16132420

Solution:Here, the pattern given below is being followed.
‘PAGE’ is coded as ‘161495’
P = 16, A = 1, G = 49 ÷ (7), E = 5
Similarly, ‘PART’ is coded as ‘16132420’.
P = 16, A = 1, R = 324 ÷ (18)² = 324, T = 20

4. In a certain code language, 'CIRCULAR' is coded as 24-3-9-24-1-15-5-9. How will 'VERTICAL' be coded as in that language? [S.S.C CGL 07/03/2020 (Morning)]

(a) 5-4-9-7-7-3-24-5-15
(b) 22-4-9-7-3-23-1-15
(c) 5-2-9-7-3-24-5-15
(d) 22-4-9-7-9-24-5-15

Correct Answer: (a) 5-4-9-7-7-3-24-5-15

Solution:Consonants are coded by the place value of their reverse letters and the vowels are numbered as A = 5, E = 4, I = 3, O = 2 & U = 1,
CIRCULAR is coded as 24-3-9-24-1-15-5-9
Similarly,

VERTICAL is coded as 5-4-9-7-3-24-5-15

Hence, '5-4-9-7-3-24-5-15' is the correct answer.
