Answers :
Direction (1-5) :
1) Answer: c)
Let the yellow ball be x,
Probability of getting one yellow ball = 1/7
xC1/(12 + x)C1 = 1/7
x/(12 + x) = 1/7
7x = 12 + x
6x = 12
x = 2
Yellow balls in bag A = 2 balls
Total probability = 14C3
The probability of getting at least one pink ball
= > 1 – P(none is pink ball)
Probability of getting none is pink ball
= >11C3 /14C3 = 165/364
The probability of getting at least one pink ball
= > 1 – (165/364) = 199/364
2) Answer: a)
Let the white ball be X,
Probability of getting one yellow ball = 1/3
5C1/(12 + X)C1 = 1/3
5/(12 + X) = 1/3
15 = 12 + X
X = 3
The total white balls in bag C = 3
Total probability = 15C4
Required probability = 3C1 and 5C1 and 4C1 and 3C1
The probability of getting different color balls
= > [3C1 and 5C1 and 4C1 and 3C1]/15C4
= > 12/91
3) Answer: d)
Let the black ball be X,
Probability of getting one yellow ball = 1/5
4C1/(15 + X)C1 = 1/5
4/(15 + X) = 1/5
20 = 15 + X
X = 5
Total number of black balls = 5
Total probability = 20C4
Required probability = 5C2 and 15C2
The probability of getting 2 pink balls from bag D
= > (5C2 and 15C2)/20C4
= > 70/323
4) Answer: b)
Let the pink ball in bag B be X,
Probability of getting one yellow ball = 3/10
6C1/(13 + X)C1 = 3/10
6/(13 + X) = 3/10
13 + X = 20
X = 7
The total number of pink ball in bag B = 7 balls
Total balls in bag B = 5 + 6 + 7 + 2 = 20
Let the yellow ball in bag E be Y,
Probability of getting one yellow ball = 1/5
YC1/(12 + Y)C1 = 1/5
Y/(12 + Y) = 1/5
5Y = 12 + Y
4Y = 12
Y = 3
The total number of yellow ball in bag E = 3 balls
Total balls in bag E = 3 + 3 + 5 + 4 = 15
Required ratio = 20 : 15 = 4 : 3
5) Answer: a)
Let the pink ball in bag B be X,
Probability of getting one yellow ball = 3/10
6C1/(13 + X)C1 = 3/10
6/(13 + X) = 3/10
13 + X = 20
X = 7
The total number of pink ball in bag B = 7 balls
Total number of pink balls in all the bags together
= > 3 + 7 + 4 + 5 + 5 = 24
Let the yellow ball in bag A be Y,
Probability of getting one yellow ball = 1/7
YC1/(12 + Y)C1 = 1/7
Y/(12 + Y) = 1/7
7Y = 12 + Y
6Y = 12
Y = 2
Yellow balls in bag A = 2 balls
Let the yellow ball in bag E be Z,
Probability of getting one yellow ball = 1/5
ZC1/(12 +Z)C1 = 1/5
Z/(12 + Z) = 1/5
5Z = 12 + Z
4Z = 12
Z = 3
The total number of yellow ball in bag E = 3 balls
Total number of yellow balls in all the bags together
= > 2 + 6 + 5 + 4 + 3 = 20
Required % = (24/20)*100 = 120 %
Direction (6-10) :
6) Answer: a)
The average working days of company B in the year 2012 and 2013 = 310 days
The total working days of company B in the year 2012 and 2013
= > 310*2 = 620 days
The number of working days of company B in the year 2012 = 620 – 308 = 312
The number of working days of company E in the year 2015
= > The number of working days of company E in the year 2014 – 17
= > 295 – 17 = 278 days
The number of working days of all the given companies in the year 2012
= > 284 + 312 + 328 + 290 + 314 = 1528
The number of working days of all the given companies in the year 2015
= > 328 + 331 + 320 + 311 + 278 = 1568
Required difference = 1568 – 1528 = 40 days
7) Answer: d)
The ratio between the number of working days of C to that of D in the year 2014 = 63 : 61
The number of working days of C in the year 2014
= > The number of working days of C in the year 2015 – 5
= > 320 – 5 = 315
63’s = 315
1’s = 5
The number of working days of D in the year 2014 = 61’s = 61*5 = 305 days
Required average = (309 + 326 + 315 + 305 + 295)/5 = 1550/5 = 310 days
9) Answer: c)
The ratio of number of working days of company D in the year 2013 to that of company A in the year 2017 = 9 : 10
9’s = 297
1’s = 33
The number of working days of company A in the year 2017 = 10’s = 330 days
The number of working days of all the given companies in the year 2016
= > 312 + 335 + 332 + 315 + 307 = 1601
The number of working days of all the given companies in the year 2017
=> 330 + 296 + 293 + 336 + 312 = 1567
Required % = (1601/1567)*100 = 102 %
10) Answer: a)
The average number of working days of company D in all the given years together = 309 days
The total number of working days of company D in all the given years together = 309*6 = 1854
The number of working days of company D in the year 2014
= > 1854 – (290 + 297 + 311 + 315 + 336)
= > 1854 – 1549 = 305 days
The total number of working days of company B and E in the year 2013 = 628
The number of working days of company E in the year 2013
= > 628 – 308 = 320 days
Required ratio = 305 : 320 = 61 : 64
10) Answer: b)
The number of working days of company A and C in the year 2015
= > 328 + 320 = 648 days
The number of working days of company B and E in the year 2017
= > 296 + 312 = 608 days
Required % = [(648 – 608)/608]*100 = 7 % more
