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?

A

N21,850

B

N18,780

C

N27,400

D

N32,500

correct option: c

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
