A. N11.7 billion
B. N13.3 billion
C. N21.7 billion
D. N26.6 billion
Correct Answer:
Option B – N13.3 billion
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 = 160/360 x 100 = 44.44%
0.444 x 60,000,000,000 = 26,640,000,000
Manufacturing sector = 80/360 x 100 = 22.22%
0.222 x 60,000,000,00 = 13,320,000,000
Difference 26,640,000,000 – 13,320,000,000 = 13,320,000,000
