Answer:
There is a total 50 questions.

Since 82% of the test was scored correctly, that means 18% of the student's exam was scored incorrectly.
With this information we can write:

25m+100−24m−75=68
Step 1: Simplify both sides of the equation.
25m+100−24m−75=68
25m+100+−24m+−75=68
(25m+−24m)+(100+−75)=68(Combine Like Terms)
m+25=68
m+25=68
Step 2: Subtract 25 from both sides.
m+25−25=68−25
m=43
Answer:
m=43
