In a class of 40 students, Anjali's rank is thrice that of Anita. There are 4 students who have ranks worse than that of Anjali. Anita's rank in the class is:

Solution

Correct Option: 4

Let Anita's rank be xx. Then Anjali's rank is 3x3x.

Since there are 4 students with ranks worse than Anjali, we have 3x+4403x + 4 \leq 40.

This simplifies to 3x363x \leq 36, leading to x12x \leq 12.

Thus, Anita's rank can be at most 12.

If x=12x = 12, then Anjali's rank would be 3636, which satisfies the condition.

Therefore, Anita's rank in the class is 1212.
