This question was asked on the 17 th of jan. 2014, a number of students was grouped according to what type of music they like. Anyone that likes rock music likes folk music, and anyone that likes rock music dislikes soul music. 12 people like only rock music, 30 people like folk music and 75 people do not like soul music represent this information using Venn's diagram and according to my memory the total number of students was 100. Please help me
