Question 1
In a class of 78 students, there are 39 boys and 39 girls. Raj ranks 12th from the top. There are 5 girls before him. How many boys are after his rank (towards the bottom)?
Students before him: 11. Of these, girls before = 5, so boys before = 11 - 5 = 6. Boys after = total boys - boys before - himself = 39 - 6 - 1 = 32.
