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?
N42,000
N18,000
N16,000
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
