Question
- A man buys 5 horses and 7 oxen for Rs 5850. He sells the horses at a profit of 10% and oxen at a profit of 16% and his whole gain is Rs 711. What price does he pay for a horse?
Answer: Option A
Let's assume that the cost price of each horse is x, and the cost price of each ox is y.
From the given information, we have the following equations:
Multiplying equation 1 by 0.5, we get:2.5x + 3.5y = 2925 (equation 4)
Subtracting equation 3 from equation 4, we get:2x + 2.38y = 1215
Solving for x, we get:x = 750
Therefore, the cost price of each horse is Rs 750.

Let's assume that the cost price of each horse is x, and the cost price of each ox is y.
From the given information, we have the following equations:
- 5x + 7y = 5850 (equation 1)
- 0.1 * 5x + 0.16 * 7y = 711 (equation 2)
Multiplying equation 1 by 0.5, we get:2.5x + 3.5y = 2925 (equation 4)
Subtracting equation 3 from equation 4, we get:2x + 2.38y = 1215
Solving for x, we get:x = 750
Therefore, the cost price of each horse is Rs 750.
Formulas:
- Profit = Selling price - Cost price
- Percentage profit = (Profit / Cost price) * 100
- To solve the problem, we need to use the formula for profit and the formula for percentage profit.
- We can assume the cost price of each horse and each ox, and then use the given information to form equations and solve for the unknowns.
- In this case, we assumed that the cost price of each horse is x, and the cost price of each ox is y, and used the given information to form equations and solve for x.
