In a class of 50 students, those who like Mathematics are 5 more than those who like science. The number of students who like science is twice as those who like mathematics and science. illustrate the information on a venn diagram. ii. find the number of students who like mathematics. iii. find the students who like mathematics only.

might be the correct answer will be question number 2

place r′ so that qr′ is parallel to the tangent.

now we get that ∠r′py=∠pr′q, where y is on the tangent, on the opposite side of p from x.

also, because of the symmetry, ∠r′py=∠qpx.

finally, note that no matter where we place r, as long as it's on the correct arc, we have ∠prq=∠pr′q.

stringing all these equalities together, we end up with ∠prq=∠qpx.

this picture will show how its going to look like.
