Question

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:

• A. 9th
• B. 12th
• C. 18th
• D. 10th

Answer 1

The Correct Option is B

Let Anjali's rank be \(A\) and Anita's rank be \(N\).

Anjali's rank is three times Anita's rank, so \(A = 3N\).

There are 4 students with ranks worse than Anjali's. This indicates Anjali's rank is \(40 - 4 = 36\).

Thus, \(A = 36\).

Substituting \(A = 36\) into \(A = 3N\), we get \(36 = 3N\), leading to \(N = \frac{36}{3} = 12\).

Consequently, Anita's rank is 12th.
