he pie chart above shows the expenditure of a family whose income is ₦30,000. If the expenditure on food is twice that on housing and that on school fees is...

Answer Details

Expenditure on housing = x
Expenditure on food = 2x
Expenditure on school fees = 90${}^{\circ }$
Expenditure on transport = 45${}^{\circ }$
x + 2x + 90 + 45 = 360${}^{\circ }$
3x + 135 = 360${}^{\circ }$
3x = 360 - 135
3x = 225
x = 225/3 = 75${}^{\circ }$
∴∠ for food = 2x = 2 * 75
= 150
360${}^{\circ }$ = N30,000
1${}^{\circ }$ = ?
1${}^{\circ }$ = 30,000/360
150${}^{\circ }$ = (30000/360) * (150/1)
= N12500
