E.None of these

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%

Required percentage = (280/560) * 100 = 50%

Required ratio = (360 + 450 + 240)/3:(280 + 560 + 480)/3

=350: 440

= 35: 44

MP = 6x

CP = 5x

11x = 4400

x = 400

CP = 400 * 5 = Rs.2000

MP = 6 * 400 = Rs.2400

SP = 2400 * 80/100 = 1920

Loss = 2000 – 1920 = Rs.80

Length of train A = 3x

Length of train B = 4x

Distance = Speed * time

Speed of train B = y

3x = 60 * 5/18 * 18

x = 100 m

Length of train B = 4 * 100 = 400 m

400 = y * 5/18 * 16

y = 90 kmph

120/4x + 120/2x = 18

(1 + 2)/4x = 18/120

x = 5

Speed of the boat in still water = 3 * 5 = 15 kmph

Speed of the stream = 5 kmph

Speed of the downstream = 15 + 5 = 20 kmph

SI = P * N * R/100

Scheme A interest = 3x * 12 * 6/100 = 216x/100

Scheme B interest = 2x * 15 * 4/100 = 120x/100

216x/100 – 120x/100 = 864

96x = 86400

x = 900

Total investment = 5x = 5 * 900 = 4500

Milk in 80 litres = 11/20 * 80 = 44 litres

Water in 80 litres = 9/20 * 80 = 36 litres

Milk in 40 litres = 11/20 * 40 = 22 litres

Water in 40 litres = 9/20 * 40 = 18 litres

(44 – 22 + 8)/(36 – 18 + x) = 1/1

30 = 18 + x

x = 12 litres
