A factory worker earns ₦50,000 per month out of which he spends 15% on his children's education, ₦13,600 on Food, 3% on electricity and uses the rest for his personal purpose. How much does he have left?
N21,850
N18,780
N27,400
N32,500
Explanation
Education = \(\frac{15}{100} \times N 50,000\)
= N 7,500
Food = N 13,600
Electricity = \(\frac{3}{100} \times N 50,000\)
= N 1,500
Leftover : N (50,000 - (7,500 + 13,600 + 1,500))
= N 27,400
