Solutions:
1. A) Percentage Decline = (80800 – 77300)/80800 * 100 = 4.33% ≈ 4%

2. B) Since the growth in the sales of automobiles in 1999-2000 as compared to 1998-1999as seen in the bar graph, is for Cars and three-wheelers only
Growth in the sales of cars in 1999-2000 as compared to 1998-1999 = 276000 – 262900 = 13100
Growth in the sales of three-wheelers in 1999-2000 as compared to 1998-1999 = 130000 122100 = 7900

3. C) Number of HCVs sold in 1998-1999 = 80400
Number of HCVs sold in 1999-2000 = 56200
Percentage Change in the sales of HCVs = (80400 – 56200)/80400 * 100 = 30%
Number of three-wheeler sold in 1998-1999 = 122100
Number of three-wheeler sold in 1999-2000 = 130000
Percentage Change in the sales of three-wheeler = (130000 – 122100)/122100 * 100 = 6.47%
Difference of percentage changes in sales of HCVs and three-wheeler = 30% - 6.47% = 23.53%

4. C) Percentage Growth = (276000 – 262900)/262900 * 100 = 4.98% ≈ 5%

5. B) Since it can be seen from the bar graph that decline in the sales of automobile is either for Two-wheelers, HCVs or LCVs in 1999-2000
Decline in the sales of Two-wheelers in 1999-2000 = 1719300 1714000 = 5300
Decline in the sales of HCVs in 1999-2000 = 80400 56200 = 24200
Decline in the sales of LCVs in 1999-2000 = 80800 77300 = 3500
Maximum decline is in the sales of HCVs in 1999-2000

6. B) Total marks obtained by Q and S together in Chemistry = (110 + 120)
= 230
Total marks obtained by P and R together in Physics = (130 + 80)
= 210
Ratio between the total marks obtained by Q and S together in Chemistry to the total marks obtained by P and R together in Physics = 230 : 210
= 23 : 21

7. D) Total marks obtained by P in Physics and Chemistry together = (130 + 90)
= 220
Total marks obtained by T in physics and Chemistry together = (50 + 60)
= 110
Ratio between the total marks obtained by P in Physics and Chemistry together to the total marks obtained by T in physics and Chemistry together = 220 : 110
= 2 : 1

8. B) Total marks obtained by T in both the subjects together = (50 + 60)
= 110
Marks obtained by Q in Chemistry = 110
Marks obtained by R in Physics = 80
Marks obtained by S in Chemistry = 120
Marks obtained by P in Physics = 130
Total marks obtained by R in both the subjects together = (80 + 100)
= 180
Therefore,
Total marks obtained by T in both the subjects together is more than the marks obtained by marks obtained by R in Physics

9. E) Marks obtained by T in Physics = 50
If the marks obtained by T in Physics were increased by 14% of the original marks
Then,
New marks of T in physics = 50 + 14% of 50
= 50 + (14/100) × 50
= 50 + 7
= 57
Maximum marks in Physics = 140
Percentage of marks obtained by T in physics = (57/140) × 100
= 40.71% ≈ 41%

10. A) Marks obtained by S in Chemistry = 120
The total marks obtained by all the students in Chemistry = (90 + 110 + 100 + 120 + 60)
= 480
Percentage of marks obtained by S in Chemistry to the total marks obtained by all the students in Chemistry = (120/480) × 100
= 25%

11. B) From the pie - chart and line graph,
Percentage of water sold by company A = 9
The sale of the company A is increased by 5%.
So, the amount of water sold by company A in 2010 = 5600000 × (14/100) = 784000 litres.
The amount of water sold by company A in 2011 = 6200000 × (14/100) = 868000 litres.
And, the amount of water sold by company A in 2012 = 7100000 × (14/100) = 994000 litres.
Hence, total amount of water sold by company A from 2010 to 2012
= (784000 + 868000 + 994000) litres = 2646000 litres.

12. B) From the pie - chart and line graph,
The total amount of water sold in 2016 = 12.7 million litres.
Percentage of water sold by company R = 21
So, the amount of water sold by company R in 2016 = 12.7 × (21/100) = 2.667 million litres.
The company R has sold the water at Rs. 20/litre. So, the turnover of the company R in 2016
= Rs. 2667000 × 20 = Rs. 53340000 = Rs. 5.334 Crores.
And,
Percentage of water sold by company B = 23
So, the amount of water sold by company B in 2016 = 12.7 × (23/100) = 2.921 million litres.
The company R has sold the water at Rs. 18/litre. So, the turnover of the company B in 2016
= Rs. 2921000 × 18 = Rs. 52578000 = Rs. 5.2578 Crores.
Hence, the difference between their turnover in that year
= Rs. (5.334 - 5.2578) Crores = Rs. 0.0762 Crores = Rs. 762000.

13. D) From the pie - chart and line graph,
The total amount of water sold in 2012 = 7.1 million litres.
We can find the top 3 and bottom 3 companies in sale of water from the percentage of water sold by different companies.
Top 3 companies = B, K, R
Bottom 3 companies = A, H, O
The amount of water sold by top 3 companies in 2012 = 7.1 × (23 + 21 + 20)% = 7.1 × (64/100) = 4.544 million litres.
And, the amount of water sold by bottom 3 companies in 2012
= 7.1 × (19 + 9 + 8) = 7.1 × (36/100) = 2.556 million litres.
The difference in the sale of water between the top 3 and bottom 3 companies in 2012
= (4.544 - 2.556) million litres = 1.988 million litres = 1988000 litres.

14. A) From the pie - chart and line graph,
The total amount of water sold in 2014 = 9.5 million litres.
We can find the company with lowest and highest sale of water from the pie - chart.
Company with lowest sale of water = H (8%)
Company with highest sale of water = B (23%)
The amount of water sold by company H in 2014 = 9.5 × (8/100) = 0.76 million litres.
The amount of water sold by company B in 2014 = 9.5 × (23/100) = 2.185 million litres.
According to the question, company B has sold water at Rs. 22/litre. So, the turnover of company B
= Rs. (2.185 × 22) millions = Rs. 48.07 millions.
The required price of water per litre = Rs. (48.07/0.76) = Rs. 63.25.

15. B) From the pie - chart and line graph,
The total amount of water sold in 2011 = 6.2 million litres.
Percentage of water sold by company B = 23
So, the amount of water sold by company B in 2011 = 6.2 × (23/100) = 1.426 million litres
Percentage of water sold by company K = 20
So, the amount of water sold by company K in 2011 = 6.2 × (20/100) = 1.24 million litres
Percentage of water sold by company H = 8
So, the amount of water sold by company H in 2011 = 6.2 × (8/100) = 0.496 million litres
Then, the total amount of water sold by these three companies in 2011
= (1.426 + 1.24 + 0.496) million litres = 3.162 million litres.
Hence, the average amount of water sold by company B, K, and H in 2011
= 3.162/3 = 1.054 million litres = 1054000 litres.
