The mark of Kiran is greater than or equal to the marks of Hina. Hina and Tina got equal marks. The mark of Tina is greater than Urvi, but Urvi's marks are less than or equal to the marks of Ira. Based on the above information, which of the following statements is/are definitely true?
I. Urvi got less marks than that of Kiran.
II. Ira's marks are less than or equal to the marks of Tina.

We know that Urvi got less than Hina and Tina. We also know that Kiran got greater than or equal to Hina and Tina. So, Kiran marks are more than Urvi even if Kiran marks are equal to the Hina's marks.

So, Statement 1 is definitely true.

We know that Ira's marks are greater than or equal to Urvi's marks. So, we don't know by how much if Ira's marks are greater than to the Urvi's marks. We know that Tina marks are more than Urvi's. So, we cannot compare the marks of Tina with Urvi's marks.

So, statement 2 cannot be determined.
