Answers:

Directions (1-5):

Bag P:

Number of pink colour caps is 15 which is 150% of the number of green colour caps. Number of black colour caps is 80% of pink colour caps. One cap is taken and the probability of getting a pink colour cap is 1/3.

Number of pink colour caps = 15

Number of green colour caps = (15/150) * 100 = 10

Number of black colour caps = (80/100) * 15 = 12

Let us take the number of red colour caps be x,

Total caps in bag P = 15+10+12+x = 37 + x

Probability of one pink cap = 15C1/(37+x)C1 = 1/3

15/(37 + x) = 1/3

45 = 37 + x

= > x = 45 – 37 = 8

Total = 45

Number of black, pink, green and red colour caps is 12, 15, 8 and 10 respectively

Bag Q:

The ratio of the number of black colour caps to the pink is 5: 6. The ratio of the number of pink colour caps to red is 4: 5. The ratio of the number of red colour caps to green is 3: 1. Two caps are taken and the probability of getting one pink and one red colour caps is 120/581.

Ratio of number of black, pink, red and green colour caps

Black   :           Pink     :           Red     :           Green

5          :           6          :           6          :           6

4          :           4          :           5          :           5

3          :           3          :           3          :           1

(5*4*3):  (6*4*3): (6*5*3)   : (6*5*1)

Ratio of number of black, pink, red and green colour caps

= 60: 72: 90: 30

= 20: 24: 30: 10

= 10: 12: 15: 5

Probability of one pink and one red colour caps

= 15xC1 *12xC1 /(10x+12x+15x+5x)C2 = 120/581

= > [(15x*12x)*2]/(42x*(42x-1)) = 120/581

= > x/(14*(42x-1))= 1/581

= > 581x = 588x – 14

= > 7x = 14

= > x = 2

Number of black, pink, red and green colour caps is 20, 24, 30 and 10 respectively.

Total = 84

Bag R:

Total number of caps is 35 more than the total number of caps in bag P. Total number of pink and red colour caps is 50% of the total number of caps. Number of pink colour cap is 150 percentage of the number of red colour caps. The number of green colour caps is 60% of the number of black colour caps.

Total = 35 + 45 = 80 caps

Number of pink and red colour caps = (50/100) * 80

= 40 caps

Number of pink colour caps = (150/100) * Number of red colour caps

Ratio of pink to red colour caps = 3: 2

Number of pink colour caps = 40*(3/5) = 24

Number of red colour caps = 40*(2/5) = 16

Number of black and green colour caps = (50/100) * 80 = 40 caps

Number of green colour caps = (60/100)*Number of black colour caps

Ratio of green to black colour caps = 3: 5

Number of green colour caps = 40*(3/8) = 15

Number of black colour caps = 40*(5/8) = 25

Number of black, pink, green and red colour caps is 25, 24, 15 and 16 respectively

Bag S:

Number of pink colour caps is equal to the number of red colour caps and 5 caps less than the number of green colour caps. Total number of caps in the bag is 5 more than bag P. one cap is taken and the probability of getting a black colour cap is 3/10.

Total = 45 + 5 = 50 caps

Number of green colour caps = x

Number of pink colour caps = Number of red colour caps = x – 5

Number of black colour caps = y

Probability of getting a black colour cap = yC1/50C1 = 3/10

y/50 =3/10

y = 15

Remaining = 50 – 15 = 35

= > x + (x -5) + (x -5) = 35

3x = 45

= > x = 15

Number of pink, black, green and red colour caps is 10, 15, 15 and 10 respectively.

Bag T:

Total number of caps in the bag is 66 (2/3)% of the total number of caps in the bag P. Number of black colour caps is one-sixth of the total number of caps and is equal to the number of red colour caps. One ball is taken and the probability of getting a green colour caps is 1/3.

Total = 66 (2/3)% of Total caps in bag P

= 200/300 * 45

= 2/3*45 = 30 caps

Number of black colour caps = 30 * (1/6) = 5 = Number of red colour caps

Number of green colour caps = x

Probability of getting a green colour cap = xC1/30C1 = 1/3

= > x/30 = 1/3

= > x = 10 caps

Number of pink colour caps = 30 – 10- 5 – 5 = 30 – 20 = 10 caps

Number of black, pink, green and red colour caps is 5, 10, 10 and 5 respectively

1) Answer: c)

Quantity I: Two caps taken randomly from the bag S. What is the probability of getting one red and one pink?

Required probability = (10C1*10C1)/50C2

= (10*10)/(50*49/(1*2))

= (10*10*2)/(50*49)

= 4/49

= 0.081

Quantity II: Two caps taken randomly from the bag T. What is the probability of getting both are pink colour?

Required probability = 10C2/30C2

= (10*9)/(30*29) = 3/29 = 0.1034

Quantity III: 7/20

7/20 = 0.35

Quantity I < Quantity II < Quantity III

2) Answer: b)

Quantity I: One cap is taken randomly from bag R, S and T. What is the probability of getting a black colour cap?

Required probability = (1/3) *(25/80 + 15/50 + 5/30)

= (1/3) * (5/16 + 3/10 + 1/6)

= (1/3) *((75+72+40)/240)

= (1/3) *(187/240)

= 187/720

= 0.2597

Quantity II: Two caps taken randomly from bag P. What is the probability of getting at least one green cap?

Required probability = 1 – Probability of none of the cap is green

= 1 – (35C2/45C2)

= 1 – ((35*34)/(45*44))

= 1 – 119/198

= 79/198

= 0.3989

Quantity I < Quantity II

3) Answer: b)

Total caps sold at 20% discount in bag Q = 84 * 25/100

= 84 * ¼ = 21

Total red caps sold at 20% discount in bag Q = 21 * 33 (1/3) %

= 21 * 1/3 = 7

Remaining red caps = 30 – 7 = 23

Required probability = (23C1/84C1)*(21C1/83C1)

= (23/84) * (21/83)

= 23/332

4) Answer: c)

Total caps in bag S after x green colour caps taken out = 50 – x

Total caps in bag T after x green colour caps added = 30 + x

Total caps in bag T after 2x red and x pink colour caps taken out

= (30 + x) – (2x + x)

= 30 – 2x

Total caps in bag S after 2x red and x pink colour caps added

= (50 – x) + (2x + x)

= 50 – x + 2x + x = 50 + 2x

In bag S, Probability of getting black colour cap is 1/6

15C1/(50+2x)C1 = 1/6

15/(50+2x) = 1/6

90 = 50 + 2x

2x = 40

= > x = 20 caps

5) Answer: d)

Quantity I: Total number of black colour caps is what percentage less than the total number of caps in bag R?

Required percentage = [(80 – 77)/80] * 100

= 3.75 %

Quantity II: Total number of green colour caps is what percentage more than the total number of caps in bag S?

Required percentage = [(69 – 50)/50] * 100

= (19/50) * 100

= 38%

Quantity III: Total number of red colour caps is what percentage more than the total number of caps in bag T?

Required percentage = [(69 – 30)/30] * 100

= (39/30)*100= 130%

Quantity I < Quantity II < Quantity III

Directions (Q. 6 – 10):

6) Answer: a)

Quantity I:

Selling price of the article = 400*(90/100) = Rs. 360

Cost price of the article

= > CP*(120/100) = 360

= > CP = 360*(100/120)

= > CP = Rs. 300

Quantity II:

Selling price of the book = 350*(92/100) = Rs. 322

Cost price of the book = 322*(100/115) = Rs. 280

Quantity I > Quantity II

7) Answer: e)

Quantity I:

According to the question,

(4800*5)/(6400*x) = (3/8)

24000/6400x = 3/8

24000*8 = 6400x*3

X = (32400*8)/(6400*3)

X = 10 months

Quantity II:

According to the question,

(5*8)/(8x) = (1/2)

X = 10 months

Quantity I = Quantity II

8) Answer: c)

Quantity I:

x/(10-6) – x/(10+6) = 6

x/4 – x/16 = 6

3x/16 = 6

X= 32 km

Quantity II:

Speed of still water (x) = 20 km/hr,

Speed of stream (y) = 8 km/hr

D = t*[(x2 – y2)/2x]

= > 4*[(202 – 82)/(2*20)]

= > 4*(400 – 64)/40

= > 4*(336/40)

= > 33.6 km

Quantity I < Quantity II 

9) Answer: c)

Quantity I:

SI = (P*n*r)/100

7500 = (P*5*8)/100

P = (7500*100)/40 = Rs. 18750

Quantity II:

C.I = P*[(1 + (r/100))2 – 1]

8800 = P*[(1 + 20/100)2 – 1]

8800 = P*[(120/100)2 – 1]

8800 = P*[(24/20)2 – 1]

8800 = P*[(576/400) – 1]

8800 = P*[176/400]

P = (8800*400)/176 = Rs. 20000

Quantity I < Quantity II

10) Answer: a)

Quantity I:

Total probability n(S) = 16C3

Required probability n(E) = 1 – P(none is Pink)

Probability of getting none is Pink balls,

P(E) = n(E)/n(S) = 11C3/16C3

= > 33/112

Required probability = 1 – (33/112) = 79/112

Quantity II:

Total probability n(S) = 16C2

Required probability n(E) = 7C2 or 4C2

P(E) = n(E)/n(S) = 7C2 or 4C2 / 16C2

= > (21 + 6)/120 = 27/120

= > 9/40

Quantity I > Quantity II
