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 answer is D

Rice = 75g, Margarine = 40g, Meat = 105g

Bread = 20g

Total = 240

Angle of sector represented by meat 

= \(\frac{105}{240} \times \frac{360^o}{1}\) 

= 157.5
