As per the given pie chart in question ,
Total number of people = 20000
The percent of maximum number of people involved in agriculture = 33.30%
The percent of minimum number of people involved in trade = 6.7%
Difference of corresponding percentages = (33.30 – 6.7)% = 26.6%
∴ Required answer = 26.6% of 20000Correct Option: D

According to given pie chart in question ,
Corresponding percentage of service = 20%
We have relation between percentage and degree ,
∴ 100% ≡ 360°∴ 1% ≡ 360 100
Correct Option: C
According to given pie chart in question ,
Corresponding percentage of service = 20%
We have relation between percentage and degree ,
∴ 100% ≡ 360°∴ 1% ≡ 360 100 ∴ 20% ≡ 360 × 20 = 72° 100
