Question #1
A man buys two items for a total of Rs. 3000. He sells one at a 20% profit and the other at a 10% loss. If he makes no overall profit or loss, what is the cost price of the first item?
A. Rs. 1500
B. Rs. 2000
C. Rs. 1200
D. Rs. 1000

Correct Answer: Option D


Explanation:
Let Cost Price of first item = x. Cost Price of second = 3000 - x. Profit = 0.20x. Loss = 0.10(3000 - x). 0.20x = 300 - 0.10x. 0.30x = 300. x = 1000.

Question #2
A trader buys two horses for Rs. 19500. He sells one at a 20% loss and the other at a 15% profit. If the selling price of both horses is the same, find the cost price of the horse sold at a loss.
A. Rs. 10000
B. Rs. 9500
C. Rs. 11500
D. Rs. 8000

Correct Answer: Option C


Explanation:
Let Cost Price 1 = C1 and Cost Price 2 = C2. C1 * 0.80 = C2 * 1.15. C1 / C2 = 1.15 / 0.80 = 115 / 80 = 23 / 16. Total parts = 39. C1 = (23 / 39) * 19500 = 11500.
