Mathematics was the Difficult section, as compared to the other two sections. Most of the questions were very specific to the coordinate Geometry chapter, only a couple of questions is from mixed chapters. This Math section had 5 difficult questions, 16 moderate questions, and 9 easy questions. There were 19 questions asked from the 12th standard syllabus and 11 questions from the 11th standard syllabus.

A sample of oleum is labeled as 104.5%. What is the percentage of free $\mathrm{SO}_3$ in the sample?
1)20%
2)40%
3)60%
4)80%
Given below are two statements: One is labelled as Assertion A and the other is labelled as Reason R.
Assertion A: Two metallic spheres are charged to the same potential. One of them is hollow and another is solid, and both have the same radii. Solid sphere will have lower charge than the hollow one.
Reason R: Capacitance of metallic spheres depend on the radii of spheres.
In the light of the above statements, choose the correct answer from the options given below.
Both and are true and is the correct explanation of
is true but is false
is false but is true 4.
Both and are true but is not the correct explanation of A
