Total Questions: 10

1. In a certain code language, PAGER is written as MIDOO. How will ANGEL be written as in that language? [S.S.C CHSL 18/03/2020 (Morning)]

(a) IKDOI
(b) AVIDI
(c) AOIDK
(d) ILVDN

Correct Answer: (a) IKDOI

Solution:For vowels, 2nd next vowels are written. While for consonants, the alphabet number is decreased by 3.

2. In a certain code language, SHARP is written as 73. How will AUDIT be written as in the same language? [S.S.C CHSL 19/03/2020 (Evening)]

(a) 80
(b) 84
(c) 76
(d) 72

Correct Answer: (a) 80

Solution:Sum of the position value of the opposite letters.
SHARP → (S ↔ H = 8) + (H ↔ S = 19) + (A ↔ Z = 26) + (R ↔ I = 9) + (P ↔ K = 11) ⇒ (8 + 19 + 26 + 9 + 11) = 73

Similarly,

AUDIT = → (A ↔ Z = 26) + (U ↔ F = 6) + (D ↔ W = 23) + (I ↔ R = 18) + (T ↔ G = 7) ⇒ (26 + 6 + 23 + 18 + 7) = 80

Hence, 80 is the correct answer.

3. In a certain code language, N is coded as 30 and COT is coded as 78. How will PET be coded as in that language? [S.S.C CHSL 12/10/2020 (Morning)]

(a) 100
(b) 70
(c) 84
(d) 41

Correct Answer: (c) 84

Solution:Code = (Sum of place value of letters × 2 + 2)

Therefore, N = (14 × 2 + 2) = 30
COT = (3 + 15 + 20) × 2 + 2 = 78
Similarly,

PET = (16 + 5 + 20) × 2 + 2 = 84
Hence, 84 is the correct answer.

4. In a certain code language, SECTION is written as PHZQLRK. How will HOSTELS be written as in that language? [S.S.C CHSL 13/10/2020 (Morning)]

(a) ERPRGIP
(b) EQPSHIP
(c) ERPQHOP
(d) FSPPQHIQ

Correct Answer: (c) ERPQHOP

Solution:The pattern in the given series is as follows:
-3, +3, -3, -3, +3, +3, -3

SECTION → (S - 3 = P)(E + 3 = H)(C - 3 = Z)(T - 3 = Q)(I + 3 = L)(O + 3 = R)(N - 3 = K) ⇒ PHZQLRK
HOSTELS → (H - 3 = E)(O + 3 = R)(S - 3 = P)(T - 3 = Q)(E + 3 = H)(L + 3 = O)(S - 3 = P) ⇒ ERPQHOP

Hence, ERPQHOP is the correct answer.

5. In a certain code language, if BURMUD is written as RKHCKT, then how will ANGLE be written as in that language? [S.S.C CHSL 14/10/2020 (Morning)]

(a) PCVAT
(b) QDWBU
(c) HOPLY
(d) REXCV

Correct Answer: (b) QDWBU

Solution:There is an decrease of 10 in each of the alphabets.
B - 10 = R, U - 10 = K, R - 10 = H, M - 10 = C, U - 10 = K, D - 10 = T
Similarly,

A - 10 = Q, N - 10 = D, G - 10 = W, L - 10 = B, E - 10 = U

Hence, QDWBU is the correct answer.

6. In a certain code language, LIFE is written as MOGI. How will SOUP be written as in the same language? [S.S.C CHSL 14/10/2020 (Afternoon)]

(a) TUVO
(b) TUOQ
(c) TUAQ
(d) TATU

Correct Answer: (c) TUAQ

Solution:In the given code, there is an increase of 1 alphabet in consonants and the next vowel is written in place of given vowels.

7. If in a code language, PATNA is coded as 260 and GOA is coded as 69, then how will you code RANCHI? [S.S.C CHSL 14/10/2020 (Evening)]

(a) 620
(b) 360
(c) 135
(d) 318

Correct Answer: (d) 318

Solution:The pattern followed here is :

Numerical position of letter get added and multiply by total number of letter to get the code.

PATNA → P(16) + A(1) + T(20) + N(14) + A(1) ⇒ (16 + 1 + 20 + 14 + 1) = 52
Total number of letters = 5

So, 52 × 5 = 260

GOA = → G(7) + O(15) + A(1) ⇒ (7 + 15 + 1) = 23

Total number of letters = 3

So, 23 × 3 = 69

Similarly,

RANCHI → R(18) + A(1) + N(14) + C(3) + H(8) + I(9) ⇒ (18 + 1 + 14 + 3 + 8 + 9) = 53
Total number of letters = 6

So, 53 × 6 = 318

Hence, 318 is the correct answer.

8. In a certain code language, TIGER is written as ROEIP. How will LION be written as in that language? [S.S.C CHSL 14/10/2020 (Evening)]

(a) JOUL
(b) JOIL
(c) JOUR
(d) JOMR

Correct Answer: (a) JOUL

Solution:Consonants take -2 with their place value and next vowels come at the place of vowels.

9. In a certain code language, NEPOLIAN is written as MCQQKGBP. How will MOHANDEV be written in that language? [S.S.C CHSL 16/10/2020 (Morning)]

(a) LMICMBFX
(b) LMICMBXF
(c) NQGCQLBFX
(d) NQICMBFX

Correct Answer: (a) LMICMBFX

Solution:

10. In a certain code language, GOLF is written as 60 and START is written as 117. How will NEST be written as in that language? [S.S.C CHSL 26/10/2020 (Morning)]

(a) 21
(b) 78
(c) 58
(d) 87

Correct Answer: (d) 87

Solution:The logic followed here is :

(Sum of place values of alphabets) × 1.5 = Given number

For GOLF = 60

(7 + 15 + 12 + 6) × 1.5 = 60

For START = 117

(19 + 20 + 1 + 18 + 20) × 1.5 = 117

Similarly,

For NEST

(14 + 5 + 19 + 20) × 1.5 = 87

Hence, 87 is the correct answer.
