Q8.
A man sells two articles for ₹99 each. On one, he gains 10% and on the other, he loses 10%. What is his overall profit or loss percentage?
1% profit
2% profit
No profit no loss
1% loss
Show answer
Answer: D. 1% loss
When two articles are sold at the same selling price, and one is sold at x% profit and the other at x% loss, there is always a loss. The loss percentage is given by (x/10)^2 %. Here, x = 10. So, Loss % = (10/10)^2 = 1^2 = 1%.

Q10.
What is the single equivalent discount for two successive discounts of 20% and 10%?
27%
28%
29%
30%
Show answer
Answer: B. 28%
For two successive discounts A% and B%, the single equivalent discount is A + B - (AB/100)%. Here, A = 20, B = 10. Equivalent Discount = 20 + 10 - (20 * 10 / 100) = 30 - (200 / 100) = 30 - 2 = 28%.
