From among those who passed Neeta is 22nd from the top and Kalyan is 22 +5 = 27th from the top and 34th from the bottom. Therefore, total number of students who passed the examination = 27 + 34 - 1 = 60.
Correct Option: C
From among those who passed Neeta is 22nd from the top and Kalyan is 22 +5 = 27th from the top and 34th from the bottom. Therefore, total number of students who passed the examination = 27 + 34 - 1 = 60.
