Directions (Q. 1 – 5):

total number of females of village Q = 40/100 x 48000 = 19200

number of literate females = 30/100 x 19200 = 5760

total number of literate population of village Q = 7/12 x 48000 = 28000

number of literate males = 28000 – 5760 = 22240

Total number of rich population of village P = 3/5 x 35000 = 21000

Total number of females of village T = (100 – 30)/100 x 30000 = 21000

Required percentage = 21000/21000 x 100 = 100%

Rich population of:

P = 3/5 x 35000 = 21000

Q = 5/6 x 48000 = 40000

R = 4/9 x 45000 = 20000

S = 1/2 x 32000 = 16000

T = 3/5 x 30000 = 18000

U = 2/5 x 25000 = 10000

Required sum = 21000 + 40000 + 20000 + 16000 + 18000 + 10000 = 125000

number of males of village S = 40/100 x 32000 = 12800

number of literate population of village S = ¾ x 32000 = 24000

number of literate males = 2/5 x 24000 = 9600

number of illiterate males = 12800 – 9600 = 3200

literate population of village R = 3/5 x 45000 = 27000

poor population of village U = 3/5 x 25000 = 15000

required percentage = (27000 – 15000)/15000 x 100 = 80%

Directions (Q. 6 -10):

Required probability = (5c1 x 2c1 x 4c1)/11c3

= (5 x 2 x 4)/165 = 8/33

total number of red balls = 4 + 5 + 6 + 3 + 4 = 22

total number of yellow balls = 3 + 2 + 5 + 4 + 2 = 16

total number of green balls = 5 + 4 + 2 + 3 + 6 = 20

required percentage = (22 + 16)/20 x 100 = 190%

Required probability = 8c4/13c4

=(8*7*6*5)/(13*12*11*10)=14/143

probability that out of 3 balls from bag S, 2 are yellow = (4c2 x 6c1)/10c3 = 36/ 120 = 3/10

probability that all the balls from bag T are green = 6c3/12c3 = 1/11

required ratio = 3/10:1/11 = 33:10

Probability of all the balls drawn from bag P are of different colours = (4c1 x 3c1 x 5c1 )/12c3

= (4 x 3 x 5)/220

= 3/11

Probability of all the balls drawn from bag R are of different colours = (6c1 x 5c1 x 2c1 )/13c3

= (6 x 5 x 2)/286

= 30/143

Required product = 3/11 x 30/143 = 90/1573
