<PRE><B>Question 1087560</B>
There are fifty students in a class. 
In a 100 marks exam, 20 students scored less than 30 marks, 5 students scored more than 70 marks and the remaining scored between 30 and 70 marks.
 If passing score is 55 marks and 40% students have passed the test, what is the percentage of students who scored between 55 and 70?
:
.40(50) = 20 students passed (above 55)
5 of those 20 students scored above 70
therefore 15 students scored between 55 and 70
{{{15/50}}} * 100 = 30% of the students scored between 55 and 70
