Directions (1 – 5):

Total number of balls in bag A = x

Total number of balls in bag B = y

Probability percentage of drawing a red colour ball from bag A

= 3/20 * 100

= 15%

Probability percentage of drawing a violet colour ball from bag A

= 100% – (20% + 30% + 25% + 15%)

= 100% – 90%

= 10%

Ratio of the number of Brown, Green, Black, Red and Violet colour balls in bag A,

= 20: 30: 25: 15: 10

= 4: 6: 5: 3: 2

Number of violet colour balls in bag A = 2/(20) * Total number of balls in bag A

4 = 2/20 * x

= > x = 40 balls

Probability percentage of drawing a violet colour ball from bag B

= 1/6 * 100

= 50/3 %

Probability percentage of drawing a red colour ball from bag B

= 100% – (20% + 25% + 25% + 50/3%)

= [300% – (60%+75%+75%+50%)]/3

= (300% – 260%)/3

= 40/3 %

Ratio of the number of Brown, Green, Black, Red and Violet colour balls in bag B,

= 20: 25: 25: 40/3: 50/3

= 60: 75: 75: 40: 50

= 12: 15: 15: 8: 10

Number of red colour balls in bag B = 8/(60) * Total number of balls in bag B

8 = 8/60 * y

= > y = 8 * 60/8

= > y = 60 balls Number of black balls in bag A = 10 + x

Total number of balls in bag A = 40 + x

Probability of drawing a black ball from bag A = (10+x)C1 / (40+x)C1 = 1/3

(10+x) / (40+x) = 1/3

30 + 3x = 40 + x

= > 2x = 10 = > x = 5

Total number of balls in bag B after taking 5 black balls

= 60 – 5 = 55

Required probability = 15C1/55C1

= 15/55 = 3/11

Probability of getting a brown ball from bag A = 8C1/40C1

= 8/40 = 1/5

Probability of getting a violet ball from bag B = 10C1/60C1

= 10/60 = 1/6

Required probability = 1/5 * 1/6 = 1/30

Probability of getting a red ball from bag A = 6C1/40C1

= 6/40 = 3/20

Probability of getting a brown ball from bag B = 12C1/60C1

= 12/60 = 1/5

Required percentage = (3/20)/(1/5) *100

= 3/20 * 5 * 100

= 75%

Probability of drawing two violet colour balls from bag B

= 10C2/60C2

Probability of drawing two violet colour balls from bag A

= 4C2/40C2

Required ratio = 10C2/60C2 : 4C2/40C2

= (10*9)/(60*59) : (4*3)/(40*39)

= (3*5*13) : (59)

= 195 : 59

Number of black colour balls in bag B = 15 + x

Number of green colour balls in bag B = 15 + 2x

Total number of balls in bag B = 60 + 3x

Probability of selecting a green colour ball from bag B = 1/3

= > (15+2x)C1/(60+3x)C1 = 1/3

(15 + 2x)/(60 + 3x) = 1/3

45 + 6x = 60 + 3x

= > 3x = 15

= > x = 5

Direction (6-10) :

Speed of train B = 72 km/hr

Speed of train E = 90 km/hr

Distance covered by train B at 11.00 am = 2 * 72 = 144 km

Total distance covered by train B and train E at 1.30 pm

= (72 + 90) * (11.00 am – 1.30 pm)

= 162 * (2 hours 30 minutes)

= 162 * (2.5)

= 405 km

Total distance between X and Y = 144 + 405 = 549 km

Owing to a signal problem arising at 12 noon,

Distance covered by Train B and Train E at 12 noon

= 2* 72 + (72 + 90)

= 144 + 162 = 306

Remaining distance = 549 – 306

= 243 km

If 243 km distance covered by two trains at 4.30 pm

Total time = (4.30 pm – 12 noon) = 4 hours 30 minutes

New speed = 243/(4.5) = 54 km/hr

Train B and Train E reduced same quantity of speed,

Let us take the reduced speed be x,

(72 – x) + (90 – x) = 54

162 – 2x = 54

162 – 54 = 2x

108 = 2x

X = 108/2 = 54 km/hr

New speed of train B = 72 – 54 = 18 km/hr

Speed of train A = 45 km/hr = 45 * 5/18 = 12.5 m/s

Speed of motor bike = 70 km/hr = 70 * 5/18 m/s

Time taken by motor bike to reach at the mid-point of the train

= 150 / (70 * 5/18 – 45 * 5/18)

= 150 * 18/5 * (1/25)

= 21.6 sec

New speed of train = 60 * 5/18

New speed of bike = 65 * 5/18

Time taken by motor bike to reach remaining 150 m

= 150/[(65 – 60)*5/18]

= 150/5 * 18/5

= 108 sec

Total distance will the motorbike travel while passing the train completely

= 21.6 * 70 * 5/18 + 108 * 65 * 5/18

= 420 + 1950

= 2370 m

= 2.37 km

Let us take the speed of train C be x km/hr,

According to the question,

18/(4x/5) – 18/x = (45 – 36)/60

(18*5)/4x – 18/x = 9/60

90/4x – 72/4x = 9/60

18/4x = 3/20

= > x = 30 km/hr

Required percentage = 30/90 * 100

= 1/3*100

= 100/3 %

Let us take the speed of train D be x km/hr and the speed of train F be (x+15) km/hr

Distance covered by train D and train F is 540 km each

Time taken by train D = 540/x

Time taken by train F = 540/(x+15) From I,

Speed of train D = 400/32 = 12.5 sec = 12.5 * 18/5

= 45 km/hr

Time taken by train D to cover 540 km

= 540/45 = 12 hours

Train D and train F will meet (6 pm + 12 hours) = 6 am

Statement I alone is sufficient to answer the question.

From II,

Speed of train F = 600/36 = 50/3 m/s = 50/3 * 18/5

= 60 km/hr

Time taken by train F to cover 540 km

= 540/60 = 9 hours

Train F and train D will meet after (9 pm + 9 hours) = 6 am

Statement II alone is sufficient to answer the question.

From I and II, either of the statement is sufficient to answer the question.

Quantity I: If 4.5 km length of the train D crosses a pole in 6 minutes, then find the speed of the train D

Speed of the train D = 4.5/(6/60)

= 4.5 * 60/6 = 45 km/hr

Quantity II: If 6 km length of the train F crosses a pole in 6 minutes, then find the speed of the train F

Speed of the train F = 6/(6/60)

= 6 *60/6 = 60 km/hr

Quantity I < Quantity II
