Their ( SOF Olympiad Trainer) solution is saying four , still they have marked 3 .

Class : Class 6

the answer should be D,4 and not C,3 as the letters in CHAIR are C,H,A,I but not R have a line of symmetry.

Class : Class 6

I think that it's a printing mistake. IN solution they are writing C,H,A,I have a line of symmetry which are 4 letters, but in the answer they are giving 3

Class : Class 6

The answer should be D. 4 as C, H, A, and I have at least a line of symmetry

Class : Class 7

my answer i 4 but they marked it wrong and showed the correct answer 3 but in the solution they are saying the answer is 4.

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%

## Ans 12:

Class : Class 7

In the solution it is given" 4 / 9 * x 3591 " but 3591 was not given in the question anywhere and the answer itself is used at the start of the solution. The question and the solution are wrong according to me.
