The given pie-chart shows the total number of children who opted different courses in a summer camp in May 2019.
300 students attended the summer camp, and every child was allowed to opt only one activity for the camp. The total number of students who opted for Yoga and Painting taken together is how much less than the total number of children who opted for Music and Dance taken together?
300 students attended the summer camp, and every child was allowed to opt only one activity for the camp. So 100% = 300 1% = 3 The total number of students who opted for Yoga and Painting taken together = (18+12)% = 30% = 30x3 = 90 total number of children who opted for Music and Dance taken together = (24+16)% = 40% = 40x3 = 120 Required answer = 120-90 = 30
