The correct answer is D. N 12500

Expenditure on housing = x

Expenditure on food = 2x

Expenditure on school fees = 90

Expenditure on transport = 45

x + 2x + 90 + 45 = 360

3x + 135 = 360

3x = 360 - 135

3x = 225

x = 225/3 = 75

∴∠ for food = 2x = 2 * 75

= 150

360

= N30,000

1

= ?

1

= 30,000/360

150

= (30000/360) * (150/1)

= N12500
