The figure is a pie chart which represents the expenditure of a family in a year. If the total income of the family was Le 10,800,000.00, how much was spent on food?

A.

Le 2,250,000.00

B.

Le 22,700,000.00

C.

Le 3,600,000.00

D.

Le 4,500,000.00

Correct answer is C

sectoral angle representing food

= 360o - (80 + 70 + 90)o

= 120o

Amount spent on food

= \(\frac{\tect{sectoral angle}}{360^o}\) x Le 10,800,000

= Le 3,600,000
