Answer:

Step-by-step explanation:

(a) 12% got 92% and above , so the number getting this from an exam entry of 250 is

250 x 12/100 = 3

(b) 86% got above 90% but less than 92%, so this is

250 x 86/100 = 215

(c) less than 90 students = 250 -3-215 = 32 students

Answer:

Answer: answers od a, b and c are 30, 215 , 5 respectively

Step-by-step explanation:

Total students who got above 92% = (12/100) ×250 = 30 students

Students who got above 90% = (86/100) ×250 = 215 students

Students who got less than 90% = (100-(86+12)))/100×250 = 5 students
