In a class of 20 students, Mridul’s rank is 12th from the top and Veena’s rank is 17th from the bottom. If Rohan’s rank is exactly between Mridul and Veenna’ rank, what is Rohan’s rank from the top ?

Answer : Option B

Explanation :

Veena’s rank from the top = 20 – 17 + 1 = 4th

Therefore, Rohan’s rank from the top = $frac{{left( {12 + 4} ight)}}{2} = 8{ m{th}}$
