Marks obtained by the seven students of a tuition class, Panchi, Qazi, Ricky, Sweta, Tiya, Urusha and Vinay, are mentioned. Panchi scored second highest marks in the class. Marks scored by Vinay was higher than only one of the person. Sweta's score was more than Tiya but less than Panchi. Three person got higher than Tiya and three got lesser than Tiya. Neither Ricky nor Qazi received the lowest marks. Given that no two students have the same marks, whose marks was the lowest?

Urusha

Seven students Panchi, Qazi, Ricky, Sweta, Tiya, Urusha, and Vinay.

1) Panchi scored the second-highest marks in the class.

So, _ > Panchi > _> _> _> _> _

2) Marks scored by Vinay were higher than only one person.

So, _> Panchi > _> _> _> Vinay> _

3) Three persons got higher than Tiya and three got lesser than Tiya.

4) Sweta's score was more than Tiya but less than Panchi.

So, _ > Panchi> Sweta> Tiya> _> Vinay> _

5) Neither Ricky nor Qazi received the lowest marks.

So, _ > Panchi > Sweta > Tiya > _> Vinay > Urusha (since Ricky and Qazi neither has got lowest marks. So, Urusha must be the one with the lowest marks)

6) This gives us the order as:

So, _> Panchi > Sweta > Tiya > _> Vinay > Urusha

7) There are two positions left to fill, for Ricky and Qazi, who should be placed higher than Vinay and lower than Tiya, Without additional information, their positions relative to each other can't be determined. Therefore, the final order could be one of the following:

So, Ricky/Qazi > Panchi > Sweta > Tiya > Qazi/Ricky > Vinay > Urusha

Therefore, Urusha scored the lowest marks.
