Solution

1) Both the quizes!

because , q3 is 85 means there are 25% students scoring more than 85 and 25% students scoring between 55 and 85.
and q3 is 90 means 25% scoring above 90 adn between 50 and 90 , there are 25%

2) for quiz A,q1 = 30 and median = 55...so,there are 25% scoring in the range 30 to 55..
and as median = 55 there will be a good concentration around 55!

for quiz 2, q1 = 35 and median = 50 , so, 25% students scoring in the range , 35 to 50 with more concentration around 50!

so, quiz B has a greater % of students with grades less than or equal to 50.....
