Mohini is taller than Nita but not shorter than Sarita. Sarita and Malini are of same height. Mohini is shorter than Hema. Among them, who is the second tallest?

The correct option is Mohini.

Let us analyze the given statements step-by-step to determine the relative heights of the individuals:

1. Mohini is taller than Nita:
Mohini > Nita

2. Mohini is not shorter than Sarita:
This means Mohini is either taller than or equal in height to Sarita:
Mohini ≥ Sarita

3. Sarita and Malini are of the same height:
Sarita = Malini

4. Mohini is shorter than Hema:
Hema > Mohini

Now, let us combine these relations to find the order of their heights:
We know that Hema is taller than Mohini (Hema > Mohini).
We also know that Mohini is taller than Nita, and Mohini is at least as tall as Sarita and Malini.
This gives us the order:
Hema > Mohini ≥ Sarita = Malini (with Mohini also being taller than Nita).

Since Hema is the only person taller than Mohini, Hema is the tallest, making Mohini the second tallest among them.
