Discounts offered by the fruit vendor on the selling price of mangoes ...
To find the maximum percentage discount a fruit vendor can give to a customer without incurring any loss, we need to analyze the profit margin and the discount offered.
Profit Margin:
Given that the fruit vendor gets a 25% profit on selling 1 dozen mangoes without giving any discount, we can calculate the cost price of 1 dozen mangoes.
Let the cost price of 1 dozen mangoes be C.
Profit = 25% of C
Selling price of 1 dozen mangoes = Cost price + Profit
= C + 0.25C
= 1.25C
Therefore, the cost price of 1 dozen mangoes is 0.8C.
Discount Analysis:
Let's consider the discount percentages offered on different quantities of mangoes.
- 5% discount on the selling price of 1 dozen mangoes.
- 10% discount on the selling price of 2 dozen mangoes.
- 15% discount on the selling price of 3 dozen mangoes.
- and so on...
Case 1: 1 Dozen Mangoes
Selling price of 1 dozen mangoes = 1.25C
Discount = 5% of 1.25C = 0.05 * 1.25C = 0.0625C
Case 2: 2 Dozen Mangoes
Selling price of 2 dozen mangoes = 2 * 1.25C = 2.5C
Discount = 10% of 2.5C = 0.1 * 2.5C = 0.25C
Case 3: 3 Dozen Mangoes
Selling price of 3 dozen mangoes = 3 * 1.25C = 3.75C
Discount = 15% of 3.75C = 0.15 * 3.75C = 0.5625C
From the above analysis, we can observe that as the quantity of mangoes increases, the discount also increases.
Maximum Discount:
To find the maximum discount, we need to find the point where the discount equals the profit margin.
Let's assume the maximum discount is offered on 'n' dozen mangoes.
Selling price of n dozen mangoes = n * 1.25C
Discount = (n * 1.25C) * (n * 0.05) = (1.25 * 0.05) * (n^2 * C) = 0.0625 * (n^2 * C)
To have no loss, the discount should be equal to the profit margin.
0.0625 * (n^2 * C) = 0.25C
Simplifying the equation,
n^2 = 4
Taking the square root on both sides,
n = 2
Therefore, the maximum discount can be offered on 2 dozen mangoes, which is 10%.
Hence, the correct answer is option C) 20%.
Discounts offered by the fruit vendor on the selling price of mangoes ...
When a fruit vendor sells 5 dozen mangoes to the customers, then the selling price after giving 25% becomes Rs. 3.75x, which is less than its cost price (Rs. 4x).
Therefore, fruit vendor can give a maximum of 20% discount to the customer.
