Priti scored more than Rahul. Yamuna scored as much as Divya. Lokita scored less than Manju. Rahul scored more than Yamuna. Manju scored less than Divya. Who scored the lowest?

Let's convert the given statements into mathematical inequalities representing scores:
Priti scored more than Rahul: Priti>Rahul

Yamuna scored as much as Divya: Yamuna=Divya

Lokita scored less than Manju: Manju>Lokita

Rahul scored more than Yamuna: Rahul>Yamuna

Manju scored less than Divya: Divya>Manju

Combining the inequalities step-by-step:

From (1) and (4): Priti>Rahul>Yamuna

From (2): Since Yamuna=Divya, we have Priti>Rahul>Yamuna=Divya

From (5): Divya>Manju, so Priti>Rahul>Yamuna=Divya>Manju

From (3): Manju>Lokita, so Priti>Rahul>Yamuna=Divya>Manju>Lokita

The final descending sequence is:

Priti>Rahul>Yamuna=Divya>Manju>Lokita
Thus, Lokita scored the lowest.
