Answers & Solutions:
1) Answer (B)
Number of chocolates with Ravi=(30/100)*350=105
Number of chocolates with Srujay=(10/100)*350=35
Number of chocolates with Praful=(20/100)*350=70
Average of chocolates receive by these three=(105+35+70)/3
=70
2) Answer (D)
Number of chocolates with Ravi=(30/100)*350=105
Number of chocolates with Srujay=(10/100)*350=35
Difference between them=105-35=70 chocolates
3) Answer (D)
Average of total cash prize received by Vince,Cena,Kofi combinedly=(16+17+29)*21/(300)
Average of total cash prize received by Orton,Roman,Kofi combinedly =(24+14+16)*21/(300)
Difference between the averages=(62-54)*21/(300)
=0.56 millions
4) Answer (B)
Percentage of cash prize won by orton=24%
Percentage of cash prize won by cena=29%
Percentage of cash prize won by vince=17%
Average of these three=(24+29+17)*21/(3*100)
=4.9 millions
5) Answer (B)
Total runs scored by Kiran,Kohli,Sehwag combinedly=(10%+30%+15%)*500=(55/100)*500
=275
Total runs scored by Virat and Rahul=(25%+20%)=(45/100)*500
=225
Difference between them=275-225=50 runs
6) Answer (C)
Percentage of runs scored by Kohli=30%
Percentage of runs scored by Virat=25%
Difference between them is 5% i.e (5/100)*500=25 runs
7) Answer (D)
The values for Tamil Nadu are: 520, 540, 550 and 520.
Since 520 repeats twice (more times than any other value), it is the mode of the observations.
8) Answer (D)
Total students appearing from Arunachal Pradesh and Jammu and Kashmir, combined in 2013 = 270 + 350 = 620
Total students appearing from Arunachal Pradesh and Jammu and Kashmir, combined in 2014 = 230 + 270 = 500
So, percentage decrease = 100* (620 – 500)/620 = 19.35%
9) Answer (B)
The number of students appearing in 2012 = 210 + 300 + 460 + 520 = 1490
The number of students appearing in 2013 = 270 + 350 + 440 + 540 = 1600
The number of students appearing in 2014 = 230 + 270 + 470 + 550 = 1520
The number of students appearing in 2015 = 250 + 310 + 490 + 520 = 1570
So, 2013 has the highest number of students.
10) Answer (B)
The mean of the scores in 2014 = $\frac{80 + 65 + 45 + 70}{4}$ = 65
So, the variance = $\frac{(65 – 80)^2 + (65-65)^2 + (65 – 45)^2 + (65 -70)^2}{4}$ = 650/4 = 162.5
Hence the standard deviation = $\sqrt{162.5}$ = 12.75
11) Answer (A)
The scores for 2012 = 80, 60, 55, 75
Arranging them in the increasing order, we get 55, 60, 75 and 80.
So, the median = $\frac{60 + 75}{2}$ = 67.5
12) Answer (C)
The range of marks (highest – lowest) for Mohit = 85 – 75 = 10
The range of marks (highest – lowest) for Archana= 65 – 60 = 5
The range of marks (highest – lowest) for Trupthi = 60 – 45 = 15
The range of marks (highest – lowest) for Neeraj = 75 – 65 = 10
So, the range is the highest for Trupthi
13) Answer (A)
Total pesticides used = 25 + 15 + 30 + 35 = 105 tons
Total fertilizers used = 30 + 40 + 15 + 25 = 110 tons
Total cost of pesticides = 2500 * 105 = 262,500
Total cost of fertilizers = 3000 * 110 = 330,000
So, the cost of fertilizers is more
14) Answer (C)
Total pesticides and fertilisers used in 2001 = 30 + 25 = 55 tons
Total pesticides and fertilisers used in 2003 = 30 + 15 = 45 tons
So, the percentage change = 100 * (55 – 45) /55 = 18.18%
15) Answer (C)
The ratio of fertilisers to pesticides in 2001 is 30 : 25
The ratio of fertilisers to pesticides in 2002 is 40 : 15
The ratio of fertilisers to pesticides in 2003 is 15 : 30
The ratio of fertilisers to pesticides in 2004 is 25 : 35
So, the lowest ratio is 15:30 (half) in the year 2003.
16) Answer (C)
The average income per company = (20 + 25 + 50 + 10)/4 = 26.25
The average expenditure per company = (30 + 10 + 40 + 30)/4 = 27.50
So, the difference = 27.5 – 26.25 = 1.25 crores
17) Answer (C)
Surplus = Income – Expenditure
The surplus for Infosys = 30 – 20 = 10 crores
The surplus for TCS= 10 – 22 = -12 crores (deficit)
The surplus for IBM = 40 – 50 = – 10 crores (deficit)
The surplus for Cognizant = 30 – 10 = 20 crores
So, 2 companies have surplus and 2 companies have a deficit
18) Answer (D)
The expenditure to income ratio for Infosys is 30 : 20
The expenditure to income ratio for TCS is 10 : 25
The expenditure to income ratio for IBM is 40 : 50
The expenditure to income ratio for Cognizant is 30 : 10
So, Cognizant has the highest expenditure to income ratio.
19) Answer (B)
A class will have less students requiring parents signatures if the same students fail in multiple subjects. So, for example, if we consider class V, the number of failures are 75% in Science. If the failures in social and maths are the same students, the maximum signatures required are for the 75% students. So, 25% didn’t need singatures
Similarly, the best case scenario for Class VI is only 55% students getting signatures.So, 45% didn’t need signatures.
Best case scenario for class VII is 80% students getting signatures. So, 20% didn’t need signatures.
Best case scenario for class VIII is 80% students getting signatures. So, 20% didn’t need signatures.
20) Answer (C)
The total percentage of students who passed in Maths from all the four classes = 35% + 75% + 20% + 20% = 150%
So, the actual number of students that passed = 150% * 40 = 60 students
