The pie chart shows the monthly expenditure pf a public servant. The monthly expenditure on housing is twice that of school fees. How much does the worker spend on housing if his monthly income is N7200?
-
A.
N1000 -
B.
N2000 -
C.
N3000 -
D.
N4000
Correct Answer: Option B
Explanation
Let the monthly expenditure on school fees be x let the monthly expenditure on housing be 2x; angle of housing and school fee in a pie chart = 360o – (120o + 90o)
= 360o – 210o = 150o
Angle of housing in a pie-chart = (frac{2}{3}) x 150 = 100
(frac{100}{360}) x 7200 = N2,000
