Correct Answer: Option n
Explanation:
(a) Total for A = 1,800,000 i.e adding the years together
Total for B = 2,300,000
Total for C = 2,900,000
Total for D = 2,200,000
Grand Total = 9,200,000
State Quantity
1998 production A = 600,000
B = 700,000
C = 800,000
D = 400,000
2,500,000
State A 600,000 = 600,000 x 360° = 6 x 360 = 432 = 86.4°
2,500,000 25 5
State B 700,000 = 700,000 x 360° = 2.520 = 504 = 100.8°
2,500,000 25 5
State C 800,000 = 800,000 x 360° = 8 x 360 = 2,880 = 576 = 115.2
2,500,000 25 25 5
State D 400,000 = 400,000 x 360° = 1440 = 57.6°
