If in a certain code, MUNDANE is coded as NFMWZMV, then how would SEQUENCE be coded?
- A.
HVFJVMXV
- B.
HVJFVMXV
- C.
HVJFVMVX
- D.
HVJFVXMV
- E.
None of these
Answer: Option B
Explanation :
Each letter in the world is replaced by the letter which occupies the same position from the other end of the English alphabetic series, to obtain the code.
As M is 13th from the front, so in code N is 13th from the last.
U is 21st from the front, so in code F is 21st from the last and so on.
Follow same for SEQUENCE to get code as HVJFVMXV.
Hence, option (b).

In a certain code language, ‘to ba vot bas’ means ‘Karan is playing cricket’, ‘cof ja ba bas’ means ‘Sundar is playing tennis’, ‘ba vot sop ho’ means ‘they are playing hockey’ and ‘to nes cof’ means ‘cricket and tennis’. Which word in that language means ‘Sundar’?
- A.
ja
- B.
bas
- C.
cof
- D.
vot
- E.
ba
Answer: Option A
Explanation :
In the first and second statements, the common code-words are ‘ba’ and ‘bas’ and the common words are ‘is’ and ‘playing’.
∴ ‘ba’ and ‘bas’ are the codes for ‘is’ and ‘playing’ in any order.
In the second and fourth statements, the common code-word is ‘cof’ and the common word is ‘tennis’.
∴ ‘cof’ stands for ‘tennis’.
So, the left word in second statement is 'Sundar' and the left code is 'ja', which is the answer.
Hence, option (a).
Workspace:
If ‘gru kia fle zo’ means ‘his city is Bokaro’, ‘mhi gru kee fle oin’ means ‘his first love is coin’ and ‘oin get fle gru ki’ means ‘coin collection is his hobby’, which word would mean ‘coin’?
- A.
gru
- B.
kia
- C.
oin
- D.
get
- E.
None of these
Answer: Option C
Explanation :
In the first and second statements, the common code-words are ‘gru’ and ‘fle’ and the common words are ‘his’ and ‘is’.
∴ ‘gru’ and ‘fle’ are the codes for ‘his’ and ‘is’ in any order.
In the second and third statements, the common code-words are ‘gru’, ‘fle’ and ’oin’ and the common words are ‘his’, ’is’ and ‘coin’.
∴ ‘oin’ stands for ‘coin’.
Hence, option (c).
Workspace:
In a certain code language. ‘719’ means ‘ice and cream’, ‘956’ means ‘ice is good’ and ‘758’ means ‘cream is cold’. Which of the following numerals is used for ‘good’?

- B.
5
- C.
6
- D.

- E.
1
Answer: Option C
Explanation :
In the first and second statements, the common code digit is ‘9’ and the common word is ‘ice’.
∴ '9' means 'ice'.
In second and third statements, the common code is ‘5’ and the common word is ‘is’.
∴ ‘5’ means ‘is’.
Thus, in the second statement, ‘6’ means ‘good’.
Hence, option (c).
Workspace:

- A.
des
- B.

We can find the code for ‘food’ as 'yar' from the second and third statements.
Now, to find the code for ‘delicious’, we need the code for ‘get’ which cannot be determined from the given information.
Hence, answer can't be determined.
Hence, option (d).
