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 represents meat in pie chart
A
30o
B
60o
C
112.5o
D
157.5o
Verified Correct Answer: D.
Step-by-Step Mathematical Solution
Rice = 75g, Margarine = 40g, Meat = 105g, Bread = 20g, Total = 240
Angle of sector represented by meat
= \(\frac{105}{240}\) x \(\frac{360^\circ}{1}\) = 157.5^\circ
