Q. Kunal, Mohit, Rohan, Sandeep, and Tarun - each have different age. Who is the oldest?
(I) Mohit is older than Kunal but younger than Sandeep.
(II) Tarun is younger than Sandeep but older than Mohit.
The question asks to identify the oldest person among Kunal, Mohit, Rohan, Sandeep, and Tarun, given two statements about their relative ages.
Statement Analysis
- Statement (I): "Mohit is older than Kunal but younger than Sandeep." This can be represented as:
- Sandeep > Mohit
- Mohit > Kunal
- Combined: Sandeep > Mohit > Kunal
- Statement (II): "Tarun is younger than Sandeep but older than Mohit." This can be represented as:
- Sandeep > Tarun
- Tarun > Mohit
- Combined: Sandeep > Tarun > Mohit
Combined Statements Analysis
Combining the information from both statements:
- From (I): Sandeep > Mohit > Kunal
- From (II): Sandeep > Tarun > Mohit
- Putting these together, we get the order: Sandeep > Tarun > Mohit > Kunal.
Sufficiency Check
The combined statements establish the relative ages of Sandeep, Tarun, Mohit, and Kunal. Sandeep is the oldest among these four.
However, the question involves five people: Kunal, Mohit, Rohan, Sandeep, and Tarun.
The age of Rohan is not mentioned or compared in either statement or their combination. Rohan could be older than Sandeep, younger than Kunal, or any age in between.
Therefore, even with both statements combined, we cannot definitively determine who is the oldest among all five individuals.
Conclusion
The data provided in both statements together is insufficient to answer the question about who is the oldest.
Important Questions from Data Sufficiency
- In this question, a question is followed by two statements numbered (I) and (II). You have to decide whether the data provided in the statements are sufficient to answer the question. Read both the statements and decide the appropriate answer.

- Area of a rectangle with length x and breadth y is P and area of a parallelogram (which is strictly not a rectangle) with adjacent sides of length x and y is Q.
Question : Is \(P > Q\)?
Statement-I: \(x : y = 2 : 1\)
Statement-II: The angle between the two adjacent sides of the parallelogram is \(60^\circ\). - A circle touches all the four sides AB, BC, CD, DA of a quadrilateral ABCD.
Question : What is the perimeter of the quadrilateral?
Statement-I: \(AB + DC = 10\) cm
Statement-II: \(AD + BC = 10\) cm
