Question 1
In a class of 71 students, there are 36 boys and 35 girls. Riya ranks 17th 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: 16. Of these, boys before = 7, so girls before = 16 - 7 = 9. Girls after = total girls - girls before - herself = 35 - 9 - 1 = 25.
