Directions (1-5) :

12 * 3 + 4 = 40

40 * 2.5 + 6 = 106

106 * 2 + 8 = 220

220 * 1.5 + 10 = 340

340 * 1 + 12 = 352

1 + 22 = 5

5 + 33 = 32

32 + 42 = 48

48 + 53 = 173

173 + 62 = 209

340 * 1.5 = 510

510 * 1.5 = 765

765 * 1.5 = 1147.5

1147.5 * 1.5 = 1721.25

1721.25 * 1.5 = 2581.875

19 + (1* 11) = 30

30 + (3 * 11) = 63

63 + (5 * 11) = 118

118 + (7 * 11) = 195

195 + (9 * 11) = 294

20 + (82 â€“ 10) = 74

74 + (72 â€“ 11) = 112

112 + (62 â€“ 12) = 136

136 + (52 â€“ 13) = 148

148 + (42 â€“ 14) = 150

Directions (6-10) :

Required ratio = 300: 240

= 5: 4

Required percentage = [150/(320 + 360)] * 100

= 22%

Total number of students from A = 160 + 120 = 280

Total number of students from C = 360 + 240 = 600

Difference = 600 â€“ 280 = 320

Average boys = (160 + 240 + 360 + 300 + 320)/5

= 276

Average girls = (120 + 150 + 240 + 280 + 360)/5

= 230

Required ratio = 276:230

= 138:115

= 6:5
