Answer: 

Direction (1-5):

1. Answer d

The probability of drawing a red ball from bag A is 3/10,

¹⁸C₁/(^18+y+g)C₁ = 3/10

18/(18+y+g) = 3/10

60 = 18+y+g

Yellow + green = 42 balls

The number of yellow and green balls present in bag A is in the ratio of 3:4

7’s = 42=> 1’s= 6

Yellow balls= 18

Green balls= 24

Total balls in bag A= 18+24+18 = 60

The probability of drawing one yellow balls if two balls are drawn from bag A at random

= > ¹⁸C₁ and ⁴²C₁ / ⁶⁰C₂

= > (18*42)/ ⁶⁰C₂

= > 126/295

2. Answer c

Total number of yellow and red balls = 60-12= 48

Number of yellow balls= 48*3/8= 18

Number of red balls = 48*5/8= 30

Required probability= ³⁰C₁*¹²C₁/⁶⁰C₂

= 12/59

3. Answer e

Let the number of green balls in bag D be x

Yellow balls = x+4

Probability of drawing one red ball= ¾

²⁴C₁/ ^x+x+4+24C₁ = ¾

24/2x+28= ¾

32= 2x+28

4= 2x

x= 2

Total number of balls= 24+2+ (2+4) = 32

4. Answer a

Number of green balls in bag B = 50- (15+12)= 23

Probability of not getting green ball= 27C3/50C3

= 117/784

Probability of getting atleast one green ball

= 1- (117/784)

= 667/784

5. Answer b

Number of green balls in bag E = 25*4/5= 20

Probability of getting either a red or green ball

= (²⁵C₁ + ²⁰C₁)/⁵⁵C₁

= (25+20)/55

= 45/55

= 9/11

 

Directions (Q. 6-10):

6) Answer b

Total number of employees from Microsoft in 2015,

520*150/100 = 780

Senior employees in Microsoft = 780*70/100 = 546

7) Answer a

The no of senior employees from IBM in 2016 is 490,

70% of total employees = 490

Total employees = 700

The ratio of Senior employees and other employees in the same year in IBM,

= > 490: 210

= > 7 : 3

8) Answer a

718*x% + 530*40% + 564*25% = 712

718*x/100 + 212 +141 = 712

718*x/100 = 359

X = 359*100/718 = 50%

9) Answer c

Average = [520*55% + 700*70% + 1020*25% + 530*40% + 610*50%]/5

= (286+255+212+302+490)/5

= 1545/5

= 309

10) Answer e

2016: 680+255+490 = 1425

2018: 660 + 305 + 270 = 1235

Diff = 1425 – 1235 =190
