The pie chart above shows the monthly distribution of a man's salary on food items. If he spent N8,000 on rice, how much did he spent on yam?

A.

N42,000

B.

N18,000

C.

N16,000

D.

N12,000

Correct answer is C

Angle of sector subtended by yam

= 360o - (70 + 80 + 50)o

= 360o - 200o

= 160o

But 80o360o x T = 8000

T = 8000×360o80o

= N36,000

Hence the amount spent on yam = 160o260×N36,000

= N16,000
