In a Group of 95 students the ratio of students who like mathematics and science is 4:5 if 10 of them like both the subject and 15 of them like none of the subject then by drawing a Venn diagram,find how many of them like math only and science only
After you sketch your Venn diagram and label the two circles M and S
place 10 in the intersection, place 4x-10 in the "only M" part and 4x-10 in
the "only S" part. Place 15 outside the two circles.
4x-10 + 10 + 5x-10 + 15 = 95
solve for x , then evaluate 4x-10 and 5x-10
