Boys from A = 5/9 * 360 = 200

Girls from A = 4/9 * 360 = 160

Total hostel fee of boys = 200 * 12000 = 2400000

Total hostel fee of girls = 160 * 10000 = 1600000

Total revenue = 2400000 + 1600000 = 4000000 = 40 lakh

Average = (450 + 280 + 560 + 480 + 240)/5

= 402

Number of boys from B = 450 * 7/15 = 210

Number of girls from B = 450 * 8/15 = 240

Number of boys from E = 5/8 * 480 = 300

Number of girls from E = 3/8 * 480 = 180

Required percentage = (240 + 180)/(300 + 210) * 100

= 82%
