In a group of four children, Som is younger to Riaz. Shiv is elder to Ansu. Ansu is youngest in the group. Which of the following statements is/are required to find the eldest child in the group? Statements 1. Shiv is younger to Riaz. 2. Shiv is elder to Som.  Correct Answer Statement 1 by itself determines the eldest child.

Given,

​Som is younger to Riaz.

Riaz > Som

Shiv is elder to Ansu.

Shiv > Ansu

Ansu is the youngest in the group.

From the given statements,

Statement 1: Shiv is younger to Riaz.

It implies that Riaz > Shiv

We know that Riaz > Som and Shiv > Ansu

So the eldest child in the group is Riaz, which we can determine by only using statement 1.

Statement 2: Shiv is elder to Som. 

Shiv > Som

Than;

Riaz/Shiv > Som > Ansu (As Ansu is the youngest in the group)

But; we cannot find who is the eldest either Riaz or Shiv.

So, statement 2 cannot determine the answer.

Hence the correct answer is option 1.
