Answer:
b) N300
Step-by-step explanation:
The cost price of an article is 100%.
If a loss off 20% was made on selling the article for N240, implies that:
The selling price which is 100% - 20% = 80% is N240.
Therefore,
Selling price 80% = N240 and
Cost price 100% =
[tex] \frac{240 \times 100}{80} = 3 \times 100[/tex]
The cost price = N300
