There are five friends --- Sachin, Kunal, Mohit, Anuj and Rohan.
Sachin is shorter than Kunal but taller than Rohan.
Mohit is the tallest.
Anuj is a little shorter than Kunal and little taller than Sachin. Who is the shortest ?

Answer: A. Rohan

Let us denote the five boys by the first letter of their names, namely S, K, M A and R.
Then,
R < S < K < M  and  S < A < K.
R < S < A < K < M.

Rohan is shortest. So, the answer is (a).
