Directions: Each of the questions below consists of a question and two statements numbered I and II given below it. You have to decide whether the data provided in the statements are sufficient to answer the question:
What is the code for ‘today’ in a coded language?
Statement I :& In the same language ‘nice day was today’ is coded as ‘ry zt dk bh’ and ‘what today was about’ is coded as ‘kj dk ry te’.
Statement II : In the same language ‘what you did today’ is coded as ‘dk ag te nd’ and ‘today was the best’ is coded as ‘lo ry dk ch’.
Statement I :& In the same language ‘nice day was today’ is coded as ‘ry zt dk bh’ and ‘what today was about’ is coded as ‘kj dk ry te’.
Statement II : In the same language ‘what you did today’ is coded as ‘dk ag te nd’ and ‘today was the best’ is coded as ‘lo ry dk ch’.
Options
- AIf the data in statement I alone is sufficient to answer the question, while the data in statement II alone is not sufficient to answer the question.
- BIf the data in statement II alone is sufficient to answer the question, while the data in statement I alone is not sufficient to answer the question.
- CIf the data either in statement I alone or in statement II alone is sufficient to answer the question.
- DIf the data in both statement I and II together are not sufficient to answer the question.
Correct answer
B.
If the data in statement II alone is sufficient to answer the question, while the data in statement I alone is not sufficient to answer the question.
Step-by-step solution
We have,
What is the code for ‘today’ in a coded language?
Statement I: & In the same language ‘nice day was today’ is coded as ‘ry zt dk bh’ and ‘what today was about’ is coded as ‘kj dk ry te’.
Statement II: In the same language ‘what you did today’ is coded as ‘dk ag te nd’ and ‘today was the best’ is coded as ‘lo ry dk ch’.
Checking Statement I:
Statement I: & In the same language ‘nice day was today’ is coded as ‘ry zt dk bh’ and ‘what today was about’ is coded as ‘kj dk ry te’.
Reference:
‘nice day was today’ is coded as ‘ry zt dk bh’
‘what today was about’ is coded as ‘kj dk ry te’
Inference:
Using the above references, we have:
nice day was today → ry zt dk bh .... (A)
what today was about → kj dk ry te .... (B)
From (A) and (B), we have:
today/was → dk/ry
Here, the code of ‘today’ is either ‘dk’ or ‘ry’ so we cannot find the answer.
Clearly, Statement I alone is not sufficient to answer the question.
Checking Statement II:
Statement II: In the same language ‘what you did today’ is coded as ‘dk ag te nd’ and ‘today was the best’ is coded as ‘lo ry dk ch’.
Reference:
‘what you did today’ is coded as ‘dk ag te nd’
‘today was the best’ is coded as ‘lo ry dk ch’
Inference:
Using the above references, we have:
what you did today → dk ag te nd .... (1)
today was the best → lo ry dk ch .... (2)
From (1) and (2), we have:
today → dk
Here, we can surely say that the code of ‘today’ is ‘dk’.
Clearly, Statement II alone is sufficient to answer the question.
Hence, the correct answer is option B.
