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)
= 3000 – 2385 = 615
6) Answer: b)

Required percentage = 1255/1425 x 100
= 88.07%
9) Answer: b)
