What is the angle of the sector representing the number of pears?
A) \[{{60}^{o}}\]
B) \[{{70}^{o}}\]
C) \[{{160}^{o}}\]
D) \[{{200}^{o}}\]
Correct Answer: B
Solution :
\[90\,\,\_\_\_\_\_\,\,180\] \[?\,\,\_\_\_\_\_\,\,400\] \[\Rightarrow \] \[400\times \frac{{{90}^{o}}}{180}={{200}^{o}}\] Angle of sector showing oranges \[={{200}^{o}}\] \[\therefore \] \[{{90}^{o}}+{{200}^{o}}+{{x}^{o}}={{360}^{o}}\] \[\Rightarrow \] \[x={{360}^{o}}-{{290}^{o}}={{70}^{o}}\]
