The pie chart shows the monthly expenditure pf ... - JAMB Mathematics 1998 Question

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 = 360^o - (120^o + 90^o)

= 360^o - 210^o = 150^o

Angle of housing in a pie-chart = \(\frac{2}{3}\) x 150 = 100

\(\frac{100}{360}\) x 7200 = N2,000
