Question #1
A man bought two horses for Rs. 30000. He sold one at a loss of 15% and the other at a profit of 19%. If the selling price of both horses is the same, what is the cost price of the second horse?
A. Rs. 17500
B. Rs. 12500
C. Rs. 10000
D. Rs. 15000

Correct Answer: Option B


Explanation:
Let the cost prices be CP1 and CP2. CP1 + CP2 = 30000. Given 0.85 * CP1 = 1.19 * CP2, which simplifies to CP1 / CP2 = 119 / 85 = 7 / 5. The ratio is 7:5. Total parts = 12. 1 part = 30000 / 12 = 2500. CP2 = 5 parts = 5 * 2500 = Rs. 12500.

Question #2
A man sold two items for Rs. 10000 each. On the first item, he gained 25%. On the second item, he lost 20%. Find his total profit or loss amount in Rupees.
A. Loss Rs. 1000
B. Profit Rs. 1000
C. Loss Rs. 500
D. Profit Rs. 500

Correct Answer: Option C


Explanation:
SP1 = 10000, Profit = 25%, CP1 = 10000 / 1.25 = 8000. SP2 = 10000, Loss = 20%, CP2 = 10000 / 0.80 = 12500. Total CP = 8000 + 12500 = 20500. Total SP = 10000 + 10000 = 20000. Total Loss = Total CP - Total SP = 20500 - 20000 = Rs. 500.

Question #3
A tradesman marks his goods 25% above the cost price and allows a 10% discount for cash payment. If he earns a profit of Rs. 50, what is the cost price?
A. Rs. 450
B. Rs. 350
C. Rs. 400
D. Rs. 380

Correct Answer: Option C


Explanation:
Let Cost Price = 100x. Marked Price = 125x. Selling Price = 125x * 0.90 = 112.5x. Profit = 12.5x. 12.5x = 50. x = 4. Cost Price = 100 * 4 = 400.
