In a class of 100 students, Nandan is 70th from the top and Arohi is 40th from the bottom. The number of students sitting between Nandan and Arohi is?

Correct option is C

Let’s break down the information given in the question:

• Nandan is 70th from the top, so there are 69 students above him.

• Arohi is 40th from the bottom, meaning there are 40 - 1 = 39 students below her.

Now, since there are a total of 100 students, we can calculate Arohi's position from the top:

• Arohi's position from the top = 100 - 40 + 1 = 61st.

Now, to find the number of students sitting between Nandan (70th) and Arohi (61st):

• The number of students between them = 70 - 61 - 1 = 8.

So, there are 8 students sitting between Nandan and Arohi.
