Directions: Each of the following 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:
Who among Meera, Jyoti, Pinki and Sadhana is the tallest?
Statement I : Meera is not as tall as Pinki or Sadhana.
Statement II : Jyoti is taller than Sadhana.
Options
- AIf the data in statement I alone are sufficient to answer the question, while the data in statement II alone are not sufficient to answer the question.
- BIf the data in statement II alone are sufficient to answer the question, while the data in statement I alone are not sufficient to answer the question.
- CIf the data either in statement I alone or in statement II alone are sufficient to answer the question.
- DIf the data even in both statements I and II together are not sufficient to answer the question.
Correct answer
D.
If the data even in both statements I and II together are not sufficient to answer the question.
Step-by-step solution
Checking S1:& Meera is not as tall as Pinki or Sadhana.
In this statement no information about Jyoti's height is given and therefore we won't be able to deduce who's the tallest among all. Thus, statement I alone is not sufficient to reach the answer.
Checking S2:& Jyoti is taller than Sadhana.
Here again, information only about Jytoi and Sadhana is given and therefore this statement alone is not sufficient to reach the answer either.&
Checking S1 and S2 together:
I.& Meera is not as tall as Pinki or Sadhana. (which implies that Meera is shorter than Pinki or Sadhana)&
II.& Jyoti is taller than Sadhana.
Using both, we get two cases
Jyoti > Pinki > Sadhana > Meera
Pinki > Jyoti > Sadhana > Meera
Clearly, even now we are not sure as in who is the tallest among all. Therefore, S1 and S2 together are not sufficient either.&
Option D is hence the correct answer.
