12:320=3:80 in its simplest form. It is not equal to 3:81. You may simplify it like 12/320 divide both numerator and denominator by 4. You will surely get the answer as 3:80.

I have confusion in statement 1 but 2nd statement are correct.
1st statement
in first no of pages in symmetry chapter is 12.
total no pages is 320.
the ratio is 12:320
=3:81 = 1 :27
2nd statement
2 out of 5 can participate means 40% of the student
the 40% of 100 is 40
the percentage of students that participate in the quiz = 40/100*100
40%
