Concentrated acid costing 90 c per litre is diluted with water in the ratio 1:5 by volume. The diluted acid is sold at 24 c per litre. What is the percentage profit?

Cost of Concentrated Acid (per liter): 90 cents

Dilution , 1 part acid to 5 parts water (total 6 parts)

Cost of Diluted Acid  -  The   mixture  cost is (1/6) * 90 cents. =15 cents

4.	Selling Price of Diluted Acid (per liter): 24 cents

5.	Profit = Selling Price−Cost Price=24−15=9 cents

Now,the percentage profit-&gt;

Cost price =15 cents

Percentage Profit=(9/15)×100≈60%

Percentage profit is  60%.
