Directions (6 – 10):

Total students = 6500

Total Boys = 6500 *(7/13) = 3500

Total Girls = 6500 *(6/13) = 3000

Boys attend art class = 15/100 * 3500 = 525

Girls attend music class = 12/100 * 3000 = 360

Total students attend art class = 30/100 * 6500 = 1950

Total girls attend art class = 1950 – 525 = 1425

Boys attend music class = 360/9*8 = 320

Boys attend dance class = 40/100 * 3500 = 1400

Boys attend sports class = 3500 – (525 + 320 + 1400)

= 1255

Girls attend dance class = 20/100 * 3000 = 600

Girls attend sports class = 3000 – (360 + 1425 + 600)
