How many students are there between Raj and Ajithain a row of 40 students ?
I.Raj is 7 from the left end, Ajitha is 17 from the right end.
II.Raj is 6 places away from Jeni, who is 20 from the left end.

Detailed Solution: Question 4

From I :
40-(7+17) = 16 children between Raj and AjithaStatement I alone:
- Raj is 7th from the left end and Ajitha is 17th from the right end.
- Total number of students between Raj and Ajitha = 40 - (7 + 17) = 16

Since the total number of students between Raj and Ajitha can be calculated using statement I alone, statement I alone is sufficient to answer the question.

Therefore, the answer is: A. If the data in statement I alone are sufficientAnalysis

Statement I: Raj is 7th from the left end and Ajitha is 17th from the right end.

Statement II: Raj is 6 places away from Jeni, who is 20th from the left end.

Statement I alone

- Raj is 7th from the left end and Ajitha is 17th from the right end.
- Total number of students between Raj and Ajitha = 40 - (7 + 17) = 16
- Therefore, Statement I alone is sufficient to answer the question.

Statement II alone

- Raj is 6 places away from Jeni, who is 20th from the left end.
- This statement alone does not provide information about the position of Ajitha.
- Therefore, Statement II alone is not sufficient to answer the question.

Since Statement I alone is sufficient to answer the question, the answer is option A.

Data Sufficiency MCQ - 3 - Question 8
Save

M’s flat is on which floor of 5 floor apartments ?
I.H flat, which is adjacent to M, is exactly below K’s flat which is on fifth floor
II.M’s flat is exactly above G’s flat, whose flat is exactly above N’s first floor flat.

Detailed Solution: Question 8

Statement I:

  • “H’s flat, which is adjacent to M, is exactly below K’s flat, which is on the fifth floor.”

    1. K is on the 5th floor.

    2. H is exactly below K ⇒ H is on the 4th floor.

    3. H is adjacent to M ⇒ M must be on a floor immediately next to H’s floor (i.e., either 3rd or 5th).

    4. But floor 5 is already taken by K, so M cannot be on 5.

    5. Hence M must be on the 3rd floor.

So Statement I alone pins M down to floor 3. It is sufficient.

Statement II:

  • “M’s flat is exactly above G’s flat, whose flat is exactly above N’s first-floor flat.”

    1. N is on the 1st floor.

    2. G is exactly above N ⇒ G is on the 2nd floor.

    3. M is exactly above G ⇒ M is on the 3rd floor.

So Statement II alone also shows M is on floor 3. It is sufficient.

Because either statement by itself suffices to place M on the 3rd floor, the correct choice is:

(c) If the data either in statement I alone or in statement II alone are sufficient to answer the question.

From I : 5 or 6 or 7 or 8 or 9 or 10 days From II : 10 or 11 or 12 or 13 or 14 days From both statements, only 10 is common in them, so Bhawna took 10 days which is predicted from bot statements.

I. A is third to the right of B, who is twelfth from the right end.
II. H is 14th from the right end of the row and there are eight students between H and A.

Detailed Solution: Question 12

From I : B is at 12th position from right, A is third to right of B, so A is 9th from right end.
From II : H is at 14th position from right, with 8 students in between A and H – it is not sure than A is left of H or right of H, so A’s position cant be predicted.

What is the code of ‘7’ in a certain code?
I. ‘734’ stands for ‘%DH’ and ‘348’ stands for ‘DH*’ in that code.
II. ‘127’ stands for $^H@’ and ‘375’ stands for ‘D@#’ in that code.

Detailed Solution: Question 13

Explanation:


  • From statement I, we can see that ‘7’ is represented as ‘%’ in the code.

  • From statement II, we can see that ‘7’ is represented as ‘&’ in the code.

  • Therefore, based on the information provided in either statement I or statement II alone, we can determine that the code for ‘7’ is either ‘%’ or ‘&’.

  • Hence, the data either in statement I alone or statement II alone is sufficient to answer the question. Therefore, the correct answer is option C.
