In preparing rice cutlets, a cook used 75g of rice, 40g of margarine, 105g of meat and 20g of bread crumbs. Find the angle of the sector which represent meat in a pie chart?
A
30\(^o\)
B
60\(^o\)
C
112.5\(^o\)
D
157.5\(^o\)
correct option: d
Rice = 75g
Margarine = 40g
Meat = 105g
Bread = 20g
Total = 240
The angle of sector represented by meat:
= \(\frac{105}{240} \times \frac{360^o}{1}\)
= 157.5
