On the basis of given graph in question ,
Accidents in the month of February = 19
Accidents in the month of January = 25
Decrease in accidents = 25  19 = 6Required percent = Decrease in accidents × 100 Accidents in the month of January
Correct Option: B
On the basis of given graph in question ,
Accidents in the month of February = 19
Accidents in the month of January = 25
Decrease in accidents = 25  19 = 6Required percent = Decrease in accidents × 100 Accidents in the month of January Required percent = 6 × 100 = 24% 25

As per the given bar graph ,
Total accidents in the city = 25 + 19 + 30 + 43 + 35 + 27 = 179
Accidents in April = 43∴ Required percent = Accidents in April × 100 Total accidents in the city
Correct Option: D
As per the given bar graph ,
Total accidents in the city = 25 + 19 + 30 + 43 + 35 + 27 = 179
Accidents in April = 43∴ Required percent = Accidents in April × 100 Total accidents in the city ∴ Required percent = 43 × 100 = 24% 179
Direction: Study the bargraph given below which shows the per cent distribution of total expenditures of a company under various expenses and answer the questions.

According to given bar graph , we have
The total expenditure of the company = $ 20 millions, Percent expenditure on transport = 12.5%
Percent expenditure on salary = 20%
Ratio of expenses on transport and salary = 12.5 : 20Correct Option: C
According to given bar graph , we have
The total expenditure of the company = $ 20 millions, Percent expenditure on transport = 12.5%
Percent expenditure on salary = 20%
Ratio of expenses on transport and salary = 12.5 : 20
Required Ratio = 125 : 200 = 5 : 8
 The ratio of the total expenditure on infrastructure and transport to the total expenditure on taxes and interest on loans is :

From the given bar diagram , we see
The total expenditure on infrastructure and transport = 20 + 12.5 = 32.5
The total expenditure on taxes and interest on loans = 10 + 17.5 = 27.5
Required ratio = The total expenditure on infrastructure and transport : The total expenditure on taxes and interest on loansCorrect Option: D
From the given bar diagram , we see
The total expenditure on infrastructure and transport = 20 + 12.5 = 32.5
The total expenditure on taxes and interest on loans = 10 + 17.5 = 27.5
Required ratio = The total expenditure on infrastructure and transport : The total expenditure on taxes and interest on loans
∴ Required ratio = 32.5 : 27.5 = 13 : 11
 If the interest on loans amounted to $ 2.45 millions, then the total amount of expenditure on advertisement, taxes and research and development is :

According to given bar graph , we have
Given , The interest on loans = $ 2.45 millions
Percentage expenditure on interest on loans = 17.5%
Percentage expenditure on advertisement, tax and research and development = 15 + 10 + 5 = 30%
∵ 17.5% ≡ $ 2.45 millionCorrect Option: B
