As we can see in the graph the maximum chart for the C is in 1995.

Number of Candidates qualified from States A and C together
= 49/100 x 15/100 x 300000 + 61/100 x 18/100 x 300000
= 22050 + 32940 = 54990
Required percentage = 54990/300000 x 100 = 18.33%

Increase in number of hotels over previous years = (number of hotels in previous year - number of hotels in current year).
Increase in number of hotels over previous years are as follows:
In 2004, 440 - 410 = 30
In 2005, 570 - 440 = 130
In 2006, 740 - 570 = 170
In 2008, 838 - 710 = 128
Hence, in 2006, increase in number of hotels over 2005 was highest.

As per given bar graph , we can see that
Total production of rice in all state = (8 + 10 + 4 + 4 + 2) = 28 Lakhs tonnes
Total production of wheat in all state = (16 + 2 + 4 + 2 + 6) = 30 Lakhs tonnes
? Required ratio = Total production of Rice : Total production of Wheat
? Required ratio = 28 : 30 = 14 : 15

From the given above figure , the minimum number of persons killed in coal mines are 150 in 2007
Hence the minimum number of persons were killed in coal mines = 150 (in 2007)

Average profit made by company A in all the years = Rs. (3 + 5 + 4 + 5 + 6 + 6)lakhs/6
= Rs. 29 /6 ? Rs. 4.83 lakh = Rs. 4,83,000

Required percentage of increase = (number of units sold in the year 2008 - number of units sold in the year 2007) x 100 / number of units sold in the year 2007
Required percentage of increase = (6.5 - 3) x 100/3 = 3.5 x 100/3 = 117%
