On the basis of given pie chart in question ,
Percent of literate males = 8%
Percent of literate females = 12%
Required difference in percentage shares = 12 – 8 = 4%
As we know that , 100% ≡ 360°Correct Option: D
On the basis of given pie chart in question ,
Percent of literate males = 8%
Percent of literate females = 12%
Required difference in percentage shares = 12 – 8 = 4%
As we know that , 100% ≡ 360°∴ 4% ≡ 360 × 4 = 14.4 ° 100
 If the difference between the two categories of people are represented by 36° in the diagram, then these categories are

As per the given pie chart in question ,
∵ 360° ≡ 100%∴ 36° ≡ 100 × 36 = 10% 360
Correct Option: A
As per the given pie chart in question ,
∵ 360° ≡ 100%∴ 36° ≡ 100 × 36 = 10% 360
∴ Difference between percentage shares of literate males literate and females = 45 – 35 = 10%
Hence , these categories are literate males and literate females .
 If two categories together have a central angle of 169.2°, then these categories are

On the basis of given pie chart in question ,
Given that , central angle of two categories = 169.2°
∵ 360° ≡ 100%∴ 169.2° ≡ 169 × 100 = 47% 360
So , Percentage share of literate females and illiterate females = (35 + 12)% = 47%Correct Option: A

According to given pie chart in question ,
Percentage of miscellaneous charges = 4%
Percentage of advertisement charges = 18%
∵ 4% ≡ $ 6000∴ 1% = 6000 4
Correct Option: B
According to given pie chart in question ,
Percentage of miscellaneous charges = 4%
Percentage of advertisement charges = 18%
∵ 4% ≡ $ 6000∴ 1% = 6000 4 Now , 18% ≡ 6000 × 18 = $ 27000 4

As per the given above histogram , we can see
Number of workers whose wages between 950 to 960 = 10
Number of workers whose wages between 960 to 970 = 5
Number of workers whose wages between 970 to 980 = 3
Number of workers whose wages between 980 to 990 = 3
Number of workers whose wages between 990 to 1000 = 5Correct Option: C
As per the given above histogram , we can see
Number of workers whose wages between 950 to 960 = 10
Number of workers whose wages between 960 to 970 = 5
Number of workers whose wages between 970 to 980 = 3
Number of workers whose wages between 980 to 990 = 3
Number of workers whose wages between 990 to 1000 = 5
Number of workers who earn more than Rs. 950 = 10 + 5 + 3 + 3 + 5 = 26
