Among five persons Sunny, Swati, Somya, Surbhi and Sapna; Swati was elder to Somya but younger to Sunny. Surbhi was elder to Sunny who was elder to Sapna who was not the youngest. Who among them was the youngest? 
1. Surbhi 
2. Somya
3. Sunny
4. Swati

Answer 1

Correct Answer - Option 2 : Somya

Five persons - Sunny, Swati, Somya, Surbhi and Sapna.

1. Swati was elder to Somya but younger to Sunny.

Sunny > Swati > Somya

2. Surbhi was elder to Sunny who was elder to Sapna who was not the youngest.

Surbhi > Sunny > Sapna > __

From 1 and 2, we get two possible cases:

Case I: Surbhi > Sunny > Sapna > Swati > Somya

Case II: Surbhi > Sunny > Swati > Sapna > Somya

Clearly, from both the cases, 'Somya' is the youngest.

Hence, ‘Somya’ is the correct answer.
