10) What is the difference between the no senior employees in 2018 and 2016 in all the Companies together, if the total no of employees from IBM in 2016 is 700?
Answer:
Direction (1-5):
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
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
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
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
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
