General Science Notes for RRB Exams (PDF)

**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
