Answer:
200
Step-by-step explanation:
Failed % candidates in accountancy = 100 - 75 = 25%.
Failed % candidates in Statistics = 100 - 70 = 30%.
//See the attached venn diagram
Percentage of students who passed both subjects =
100 - (2 + 23+7) = 68%.
So 68% of students = 136
Total number of students = 136 * 100/68 = 200.
