Answer:96 students
Step-by-step explanation:
total number of pupils = 200
number that scored above 90 = 20% of 200 = 20/100 x 200
= 0.2 x 200 = 40 students
remainder of students = 200 - 40 = 160 students
students that scored between 70 and 90 = 40% of remainder
= 40 % OF 160 = 40/100 X 160
= 0.4 X 160 = 64 students
students that scored below 70 marks = remainder of students - students that scored between 70 and 90 marks
= 160-64 = 96 students.
