## Coding-Decoding Questions & Answers for IB ACIO Exam PDF (Hindi)

### Here a few questions as stated in the PDF:

1. In a certain code language, ‘dee due tic’ is written as ‘roses are red’, ‘bil doe’ is written as ‘yellow carnations’ and ‘tic dur doe’ is written as ‘carnations are pink’. What is the code for ‘pink’ is that language?

A. doe
B. tic
C. dur
D. dee
Solution: ‘dee due tic’ = ‘roses are red’_________(1)

‘bil doe’ = ‘yellow carnations’ ___________(2)

‘tic dur doe’ = ‘carnations are pink’_________(3)

'are' and 'tic' are common in (1) and (3), so 'are' = 'tic'

'carnations' and 'doe' are common in (2) and (3),

So, 'carnations' = 'doe'

from (3), 'pink' = 'dur'

Hence, the correct option is C.

2. If KIND is written as 20 and MOBILE is coded as 42, then how will you write PRIMARY in the same language?

A. 42
B. 36
C. 56
D. 78
Solution: The logic behind the code language is - number of letters in the word multiplied by its succeeding number.

i.e. In KIND - there are 4 letters

So, 4 × 5 = 20

Similarly,

MOBILE = 6 × 7 = 42

So,

PRIMARY = 7 × 8 = 56

Hence, option C is the correct answer.

3. If EFMIJ means DELHI, then find the last letter of IQBOS after decoding –

A. T
B. R
C. K
D. M
Solution: E (-1) = D
F (-1) = E
M (-1) = L
I (-1) = H
J (-1) = I
Similarly,
I (-1) = H
Q (-1) = P
B (-1) = A
O (-1) = N
S (-1) = R

Thus, R is the last letter.

Hence, option B is the correct answer.

4. In a code language. RAMAYANA is written as ANAYAMAR. How will MAHABHARAT be written as in that language?

A. TARAHBAHAM
B. TARBHAAHAM
C. TARAHBAMAH
D. ARATHBAHAM
Solution:

Logic: Letter has been written in the reverse order.

As, RAMAYANA = ANAYAMAR

Similarly,

MAHABHARAT=TARAHBAHAM

Hence, the correct answer is option A.

5. In a certain code language, COMPUTRONE is written as PMOCTUENOR. How is ADVANTAGES written in that code?

B. AVDATNSEGA
C. AVDATASEGN
D. NAVDASEGAT

Solution:

Logic: The first four letters, the middle two letters and the last four letters of the word are written in a reverse order to form the code.
COMPUTRONE is written as:-
COMP  ⇒ PMOC
UT ⇒ TU
RONE  ⇒ ENOR
So, "COMPUTRONE" is coded as "PMOCTUENOR".
Similarly,
ADVANTAGES is written as:-
NT   TN
AGES  ⇒ SEGA
So, "ADVANTAGES" is coded as "AVDATNSEGA".
Hence, option B is the correct answer.

6. If NASCENT is written as 2734526, how is SENTENCE written in that code?

A. 35265235
B. 35256245
C. 35265245
D. 35256275
Solution:

NASCENT → 2734526,
N → 2; A → 7; S → 3; C → 4; E → 5; N → 2; T → 6
Using the number codes of the above letters we get:
SENTENCE
S → 3; E → 5; N → 2; T → 6; E → 5; N → 2; C → 4; E → 5
So, SENTENCE → 35265245
Hence, option C is the correct answer.
