Solution
The correct option is D Cannot be determined
From the frequency table we get the classes as '20-40', '40-60', '60-80' and '80-100'. For these classes, we find the frequency but for the interval 30 to 50, we cannot find the exact frequency. So we cannot determine how many students scored between 30 to 50.
