Q. A man sells two articles for $120 each. If he makes a profit of 20% on the first article and a loss of 20% on the second article, what is his overall profit or loss percentage?
A.
0%
B.
5%
C.
10%
D.
15%
Solution
Cost price of first article = 120 / 1.2 = $100. Cost price of second article = 120 / 0.8 = $150. Total cost price = 100 + 150 = $250. Total selling price = 120 + 120 = $240. Loss = 250 - 240 = $10. Loss percentage = (10 / 250) * 100 = 4%.

Q. A mixture contains 30% alcohol and 70% water. If 10 liters of the mixture is taken out, how much alcohol is left in the mixture?
A.
3 liters
B.
4 liters
C.
5 liters
D.
6 liters
Solution
In 10 liters of the mixture, alcohol = 30% of 10 = 3 liters. If the original mixture was 10 liters, the remaining alcohol = 30% of (original volume - 10) = 30% of (10 - 10) = 0 liters. Thus, 3 liters of alcohol is removed, leaving 0 liters.
