In a class of 77 students, there are 31 boys and 46 girls. Meera ranks 24th from the top. There are 10 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 = 10, so girls before = 23 - 10 = 13. Girls after = total girls - girls before - herself = 46 - 13 - 1 = 32.
