Correct Answer: Option B
Explanation:
The summation of a piechart is 360°. To get the figure for manufacturing sector we simply add the figures for oil, agriculture and mining sector and minus it from 360. Thus we have;
160 + 90 + 30 = 280
360 - 280 = 80
Manufacturing sector = 80°
The difference between Oil sector and manufacturing sector =
Oil sector = \(\frac{160}{360}\) x 100 = 44.44%Â
0.444Â x 60,000,000,000 = 26,640,000,000
Manufacturing sector = \(\frac{80}{360}\) x 100 = 22.22%
 0.222 x 60,000,000,00 = 13,320,000,000
Difference 26,640,000,000 -Â 13,320,000,000 = 13,320,000,000
