Question 1
In a class of 77 students, there are 36 boys and 41 girls. Riya ranks 24th from the top. There are 7 boys before her in the rank list. How many girls are after her rank (towards the bottom)?
Students before her: 23. Of these, boys before = 7, so girls before = 23 - 7 = 16. Girls after = total girls - girls before - herself = 41 - 16 - 1 = 24.
