Answers:
Directions (Q1 – 5):
Q1. Answer: c
In bag Q:
Red = 8
Green = 7
Blue = 12
Yellow = 5/4 x 8 = 10
Total = 37
Required probability =(8c1 x 7c1 x 12c1 x10c1)/37c4
= (8 x 7 x 12 x 10)/66045
= 64/629
Q2. Answer: b
In bag R:
Red = 10
Green = 12
Blue = 4
Yellow = 7/5 x 10 = 14
Total = 40
Probability of drawing 2 red and 1 blue ball from bag R = (10c2 x 4c1)/40c3
= (45 x 4)/9880
= 9/494
Now,
In bag S:
Red = 12
Green = 6
Blue = 5
Yellow = 4/3 x 12 = 16
Total = 39
Probability of drawing 2 red and 1 blue ball from bag S = (12c2 x 5c1)/39c3
= (66 x 5)/9139
= 330/9139
Required ratio = 9/494 : 330/9139 = 27417:54340
Q3. Answer: a
In bag T:
Red = 15
Green = 13
Blue = 7
Yellow = 3/5 x 15 = 9
Total = 44
Probability of drawing three green balls from bag T = 13c3/44c3
= 286/13244
= 13/602
In bag U:
Red = 14
Green = 5
Blue = 10
Yellow = 6/7 x 14 = 12
Total = 41
Probability of drawing three yellow balls from bag U = 12c3/41c3
= 220/10660
= 11/533
Required percentage = (13/602)/(11/533) x 100 = 104.63%
Q4. Answer: d
Total number of green balls in all the bags together = 11 + 7 + 12 + 6 + 13 + 5 = 54
Total number of yellow balls in all the bags together
= 3/2 x 4 + 5/4 x 8 + 7/5 x 10 + 4/3 x 12 + 3/5 x 15 + 6/7 x 14
= 6 + 10 + 14 + 16 + 9 + 12
= 67
Required percentage = (67 – 54)/54 x 100 = 24.07% more.
Q5. Answer: c
In bag P:
Red = 4
Green = 11
Blue = 16
Yellow = 3/2 x 4 = 6
Total = 37
Probability of drawing 2 green and 2 yellow balls from bag P = (11c2 x 6c2)/37c4
= (55 x 15)/66045
= 55/4403
In bag U:
Red = 14
Green = 5
Blue = 10
Yellow = 6/7 x 14 = 12
Total = 41
Probability of drawing 2 red and 2 blue balls from bag U = (14c2 x 10c2)41c4
= (91 x 45)/101270
= 819/20254
Required product = 55/4403 x 819/20254
= 45045/89178362
Directions (Q. 6 – 10):
Amount invested by A, B and C on SI = 15000 + 35000 + 30000 = 80000
Amount invested by D, E and F on CI = 50000 + 10000 + 30000 = 90000
Required percentage = (80000/90000) x 100 = 88.88%
Amount of A after three years = 40000 x 115/100 x 115/100 x 115/100 = Rs.60835
Amount of D after five years = (45000 x 18 x 5)/100 + 45000 = 40500 + 45000 = Rs.85500
Required ratio = 60835 : 85500 = 12167 : 17100
Simple interest earned by B after 10 years at the rate of 8% per annum = (35000 x 10 x 8)/100
= Rs.28000
Simple interest earned by F after 12 years at the rate of 5% per annum = (25000 x 12 x 5)/100
= Rs.15000
Required percentage = (28000 – 15000)/15000 x 100 = 86.67%
Amount earned by B on compound interest at the rate of 10% after 2 years
= 20000 x 110/100 x 110/100
= Rs.24200
Amount earned by C on compound interest at the rate of 10% after 3 years
= 25000 x 110/100 x 110/100 x 110/100
= Rs.33275
Amount earned by D on compound interest at the rate of 10% after 4 years
= 50000 x 110/100 x 110/100 x 110/100 x 110/100
= Rs.73205
Required sum = 24200 + 33275 + 73205 = Rs.130680
Sum of amounts invested by all the persons in simple interest
= 15000 + 35000 + 30000 + 45000 + 20000 + 25000
= 170000
Sum of amounts invested by all the persons in compound interest
= 40000 + 20000 + 25000 + 50000 + 10000 + 30000
= 175000
Required percentage = (175000 – 170000)/175000 x 100 = 2.85% less
