Coding Decoding: Bank Exam Practice Questions (SBI, IBPS, RRB, PO & Clerk)

Ans: A

Explanation: The question states that “honesty will not perish” is coded as “Z0, F2, N9, S6”. The code “Z0” appears first in the coded sentence and corresponds to the first word in the uncoded sentence which is “honesty”.
Correct Option: A

Ans: A

Explanation:
1. **Identify common words and codes:**
* “and” appears in sentences 1, 2, and 4. The corresponding codes are “li”, “so”, “da”, and “li”. This identifies “li” or “so” for “and”. Since “and” appears multiple times, “li” and “so” can correspond to “and”.
* “shine” appears in sentences 2 and 4. The corresponding codes are “pe” and “pe”. So, “pe” must correspond to “shine”.
* “moon” appears in sentences 1 and 2. The codes are “so”, and “li”.
2. **Determine the codes for “and shine”:**
From above “and” = li/so, “shine” = pe. Thus “and shine” corresponds to li pe or so pe. Since so is present in “moon and”, and moon also has so. Hence “so” corresponds to moon.
3. Therefore “and shine” = li pe.

Ans: A

Explanation:
1. **Identify common words and codes:**
– “sun” appears in sentences 1 and 3, and the common code is “ja”.
– “rises” appears in sentences 1 and 4, and the common code is “li”.
– “east” appears in sentences 1 and 2, and the common code is “to”.
– “day” appears in sentences 2, 3 and 4.
2. **Determine the remaining code:**
– From sentence 3, the codes are “ja pa to ze”. We know “ja” represents “sun” and “to” represents “east”. Also, “day” appears in this sentence and it also occurs in the last sentence. From the last sentence, we know that “li” is “rises”. From sentence 3, we know that “pa” represents “also” and “ze” represents “shines”
3. **Find the code for ‘shines’:** In sentence 3, “sun day also shines” is written as “ja pa to ze.” We found that “ja” represents “sun”, “to” represents “east” and “pa” represents “also”. Therefore, “ze” represents “shines.”

Ans: B

Explanation:
1. **Identify common words and codes:**
* ‘water is life’ = ‘do ma ki’ and ‘life is precious’ = ‘ki sa do’ share ‘life’ and ‘is’. The codes ‘ki’ and ‘do’ appear in both.
* ‘water is life’ = ‘do ma ki’ and ‘water and drink’ = ‘ma fu je’ share ‘water’. The code ‘ma’ appears in both.
* ‘drink and beautiful’ = ‘je fu ra’ and ‘water and drink’ = ‘ma fu je’ share ‘drink’ and ‘and’. The codes ‘fu’ and ‘je’ appear in both.
* Therefore, since ‘life’ and ‘is’ are represented by the codes ‘ki’ and ‘do’, and we know ‘life is precious’ = ‘ki sa do’, the remaining code ‘sa’ must represent ‘precious’.

Ans: E

Explanation:
1. **Identify common words and codes:**
* “market open today” – “la ki zo”
* “today close sale” – “ki ju ga”
* “open sale buy” – “ga zo fu”
* “market buy now” – “fu la de”

2. **Solve for “today”**: “today” is common to the first and second sentences. “ki” is the only common code between them. Hence, “today” = “ki”

3. **Solve for “open”**: “open” is common in sentence 1 and 3. The common code is “zo”. Hence, “open” = “zo”.

4. **Solve for “sale”**: “sale” is common in sentence 2 and 3. The common code is “ga”. Hence, “sale” = “ga”

5. **Solve for “market”**: “market” is common to sentence 1 and 4. The common code is “la”. Hence, “market” = “la”

6. **Solve for “buy”**: “buy” is common in sentence 3 and 4. The common code is “fu”. Hence, “buy” = “fu”

7. **Solve for “now”**: The code remaining from sentence 4 is “de”. Therefore, “now” = “de”.

Ans: D

Explanation:
1. **Identify common words and codes:**
– ‘always’ is common in sentences 1 and 2, and ‘xly’ is common in their codes. So, ‘always’ = ‘xly’.
– ‘focus’ is common in sentences 1 and 2, and ‘rsg’ is common in their codes. So, ‘focus’ = ‘rsg’.
– ‘mind’ is common in sentences 2 and 3, and ‘kpd’ is common in their codes. So, ‘mind’ = ‘kpd’.
– ‘try’ is common in sentences 1 and 3, and ‘zfq’ is common in their codes. So, ‘try’ = ‘zfq’.
– From sentence 2, ‘the’ = ‘bvd’
– From sentence 3, ‘action’ = ‘jpm’

2. **Determine the codes for ‘the action’:**
– Therefore, the code for ‘the action’ is ‘bvd jpm’.

3. **Check the options:**
– None of the given options matches ‘bvd jpm’, so we must have made an error or the options are wrong. However, since we’ve identified that “mind” = “kpd” from sentences 2 & 3, and the code for ‘the’ has to be bvd. Thus we conclude that ‘the’ = ‘bvd’ and ‘action’ = ‘jpm’

Ans: C

Explanation:
1. **Identify common words and codes:**
* ‘days’ appears in sentences 1 and 2, and ‘re’ appears in both. So, ‘re’ likely represents ‘days’.
* ‘sunny’ appears in sentences 1 and 3, and ‘si’ appears in both. So, ‘si’ likely represents ‘sunny’.
* ‘are’ appears in sentences 2 and 4, and ‘ka’ appears in both. So, ‘ka’ likely represents ‘are’.
2. **Deduce the code for ‘cloudy’:**
* In sentence 2, ‘days are cloudy’ is ‘re ka’, and we know ‘re’ is ‘days’ and ‘ka’ is ‘are’. Therefore, the remaining code ‘ka’ must be ‘cloudy’.

3. In sentence 3, ‘sunny and cloudy’ is ‘si ka’, and we know ‘si’ is ‘sunny’ and ‘ka’ is the code for ‘cloudy’

Therefore, the code for ‘cloudy’ is ‘ka’.

Ans: C

Explanation:
1. Identify common words and their codes:
* ‘bright’ appears in sentences 1 and 3, and ‘fe’ appears in both. So, ‘fe’ likely represents ‘bright’.
* ‘sunny’ appears in sentences 1 and 2, and ‘ka’ appears in both. So, ‘ka’ likely represents ‘sunny’.
* ‘pleasant’ appears in sentences 2 and 3, and ‘zo’ appears in both. So, ‘zo’ likely represents ‘pleasant’.

2. Determine the remaining codes:
* In sentence 1, ‘days’ is left, and ‘gi’ is left. Therefore, ‘gi’ represents ‘days’.

3. The question asks for the code for “days”.

Ans: D

Explanation:
1. **Identify common words and codes:**
* ‘future’ appears in sentences 1 and 2, and ‘fu’ is common to both. Therefore, ‘fu’ likely represents ‘future’.
* ‘bright’ appears in sentences 1 and 3, and ‘gi’ is common to both. Therefore, ‘gi’ likely represents ‘bright’.
* ‘looks’ appears in sentences 2 and 3, and ‘zo’ is common to both. Therefore, ‘zo’ likely represents ‘looks’.

2. **Deduce the remaining codes:**
* In sentence 3 (‘looks bright today’ – ‘zo gi re’), we know ‘zo’ is ‘looks’ and ‘gi’ is ‘bright’. Therefore, ‘re’ must represent ‘today’.

Ans: B

Explanation: We need to find the code for “orange”.

* “red and blue” = “sa ta da”
* “green and white” = “ga ta ma”
* “blue green orange” = “da ga ka”

“blue” and “green” both appear in the third sentence and we can see that ‘da’ and ‘ga’ are common to the first two sentences and the third sentence. Thus, ‘orange’ must be coded as ‘ka’.

Ans: E

Explanation: First, let’s identify the codes for common words.
‘Study hard and achieve’ (ze ki po lu)
‘Achieve your goal’ (lu na gi)
‘Goal is to study’ (gi vo ze)
‘Hard work is necessary’ (vo ki bl)

From the first and third sentences, ‘study’ is coded as ‘ze’.
From the first and second sentences, ‘achieve’ is coded as ‘lu’.
From the second and third sentences, ‘goal’ is coded as ‘gi’.
From the first and fourth sentences, ‘hard’ is coded as ‘ki’.
The fourth sentence gives us the codes for ‘work’ and ‘necessary’, which are ‘bl’ and ‘vo’.
Therefore, the code for ‘work’ is ‘bl’ and ‘necessary’ is ‘vo’.

Ans: B

Explanation: The code appears to shift each letter one position forward in the alphabet.
K becomes L, E becomes X, Y becomes B, B becomes C, O becomes N, A becomes S, R becomes M, D becomes M.

Applying the same logic to STRING:
S becomes T, T becomes U, R becomes S, I becomes J, N becomes O, G becomes H.
