Direction (1-5)

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 % = [(22 + 16)/20]*100 = 190 %

Probability of taking at least one yellow ball = 1 – P(none is yellow ball)

P(None is yellow ball)

= > 8C4/13C4

= > 14/143

Probability of taking at least one yellow ball = 1 – (14/143) = 129/143

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 colors

= (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 colors

= (6c1 x 5c1 x 2c1)/13c3

= (6 x 5 x 2)/286

= 30/143

Required product = (3/11)*(30/143) = 90/1573

Direction (6-10)

Population of village A above poverty line

= > 120*(13/100)*(55/100) = 8.58 lakhs

Population of village C above poverty line

= > 120*(8/100)*(40/100) = 3.84 lakhs

Required difference = 8.58 – 3.84 = 4.74 lakhs

(30/100)* Total population of village G = 9 lakhs

Total population of village G = (9/30)*100= 30 lakhs

Total population of all the villages = (30/15)*100= 200 lakhs

Difference between number of males and females in village E

= > 200*(18/100)*(2/12) = 6 lakhs

Male population of village F in 2006 = (10/250)*100 = 4 lakhs

Total population of village F in 2006 = 4*2 = 8 lakhs

The number of people above poverty level in Village F in 2006

= > 8*(75/100) = 6 lakhs

Total population of all the villages = (99/33)*100 = 300 lakhs

Male population in village C = (8/100)*300*(5/12) = 10 lakhs

Female population in village A= (13/100)*300*(7/13) = 21 lakhs

Required difference = 21 – 10 = 11 lakhs

Total population of Village G = (18/30)*100 = 60 lakhs

Total population of all the village = (60/15)*100 = 400 lakhs

Male population of village E = 400*(18/100)*(7/12) = 42 lakhs

Female population of village E = 400*(18/100)*(5/12) = 30 lakhs

Required percentage = [(42 – 30)/30]*100 = 40%
