Q. Harsh, Ketan, Mayank, Rohit, and Sidharth, each have different height. Who is the shortest?
(I) Mayank is taller than Harsh but shorter than Ketan.
(II) Rohit is taller than Harsh but shorter than Mayank.
The question asks to identify the shortest person among Harsh, Ketan, Mayank, Rohit, and Sidharth using two statements about their heights.
Statement (I) provides the following information:
Combining these, we get the order: $Ketan > Mayank > Harsh$. This tells us Harsh is shorter than Ketan and Mayank. However, the heights of Rohit and Sidharth are unknown relative to this group. Therefore, Statement I alone is not sufficient.
Statement (II) provides the following information:
Combining these, we get the order: $Mayank > Rohit > Harsh$. This tells us Harsh is shorter than Mayank and Rohit. However, the heights of Ketan and Sidharth are unknown relative to this group. Therefore, Statement II alone is not sufficient.
Combining the information from both statements:
Putting them together, we can establish the following partial order:
$Ketan > Mayank > Rohit > Harsh$
This combined information shows that Harsh is shorter than Ketan, Mayank, and Rohit. However, the position of Sidharth is not mentioned in either statement. Sidharth could be shorter than Harsh, making Sidharth the shortest, or Sidharth could be taller than Ketan, or anywhere in between. Since Sidharth's height is unknown, we cannot definitively determine who is the shortest person.
Both statements, when combined, are insufficient to answer the question because the height of Sidharth is unknown.
Below is given a pair of questions, which are required to be answered, and a triad of statements. Which group of statements is sufficient to answer both the questions?
Question 1: Who is sitting opposite to Q?
Question 2: Who is sitting to the right of Q?
Statement 1 : P and U are sitting on left and right sides of T, respectively
Statement 2: P, Q, R, S, T and U are sitting around a round table with six chairs
Statement 3: Q is NOT sitting on the immediate left side of R
