Question

in an examination 95% of the students passed and 35 failed. how many students wrote the examination

Answer 1

x(100-95)/100 = 35
x5/100 = 35
x = 700

Answer 2

Therefore,
Total number of students in examination = x
The total number of students passed = 95/100x
Therefore,
x - 95x/100 = 35
5x/100 = 35
5x = 3500
x = 700
Total number of students who wrote the exam are 700.
