From the given pie chart in question ,
Difference between corresponding angles for English and Science = 80° – 55° = 25°
Difference between corresponding angles for Maths and Social Science = 90° – 65° = 25°Correct Option: D
From the given pie chart in question ,
Difference between corresponding angles for English and Science = 80° – 55° = 25°
Difference between corresponding angles for Maths and Social Science = 90° – 65° = 25°
Hence , The difference of marks between English and Science is the same as between Mathematics and Social science

According to given pie chart in question ,
Total marks obtained = 540
Corresponding angle for Hindi = 70°
∵ 360° ≡ 540∴
1° =540 360
Correct Option: B
According to given pie chart in question ,
Total marks obtained = 540
Corresponding angle for Hindi = 70°
∵ 360° ≡ 540∴
1° =540 360 ∴ 70° ≡ 540 × 70 = 105 360
Hence , required answer is Hindi .

From the given pie chart in question ,
Corresponding angle for English, Science and Social Science = 55° + 80° + 65° = 200°
Corresponding angle for Hindi and Maths = 90 + 70 = 160°
Change in corresponding angle = 200 - 160 = 40∴ Required percent = Change in corresponding angle × 100 Corresponding angle for Hindi and Maths
Correct Option: C
From the given pie chart in question ,
Corresponding angle for English, Science and Social Science = 55° + 80° + 65° = 200°
Corresponding angle for Hindi and Maths = 90 + 70 = 160°
Change in corresponding angle = 200 - 160 = 40∴ Required percent = Change in corresponding angle × 100 Corresponding angle for Hindi and Maths Required percent = 40 × 100 = 25% 160

On the basis of given pie chart in question ,
Sum of the corresponding angles for steel, cement and miscellaneous items = (36° + 72° + 108°) = 216°
∵ 360° ≡ 100%∴
1° =100 360 ∴ 216° ≡ 100 × 216 = 60% 360
Correct Option: C

From the given pie chart in question ,
The cost of cement = $ 5000
Corresponding angle for cement = 72°
Corresponding angle for labour expenses = 90°
∵ 72° ≡ $ 5000∴
1° =5000 72
Correct Option: B
From the given pie chart in question ,
The cost of cement = $ 5000
Corresponding angle for cement = 72°
Corresponding angle for labour expenses = 90°
∵ 72° ≡ $ 5000∴
1° =5000 72 ∴ 90% ≡ $ 
5000 × 90° 
= $ 6250 72°
