Answer:
500 marks
Step-by-step explanation:
let the total mark of the examination be x
students gets= 26% of x
pass mark =40% of x
students fails by=40% of x -26% of x
=14% of x
but students fails by 70 marks,
therefore,
14% of x =70
14/100 × x = 70
x =70×100/14
x=500
The total mark of the examination is 500.
