Ask EduPadi AI for a detailed answer

Correct Option: D

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