400 Mangoes were purchased at Rs. 125 per hundred and sold at a loss of Rs. 100. Find the Selling price of one dozen mangoes.

To solve this, let's break it down step by step.

Step 1: Cost Price Calculation
The cost price of 400 mangoes is given as Rs. 125 per hundred.

So, the cost price for 400 mangoes will be:

Cost price for 400 mangoes = (400 / 100) * 125
Cost price for 400 mangoes = 4 * 125 = Rs. 500

Step 2: Selling Price Calculation
The mangoes were sold at a loss of Rs. 100. So, the selling price is:

Selling price = Cost price - Loss
Selling price = 500 - 100 = Rs. 400

Step 3: Selling Price Per Mango
The total selling price for 400 mangoes is Rs. 400. Therefore, the selling price for one mango is:

Selling price per mango = 400 / 400 = Rs. 1 per mango

Step 4: Selling Price for One Dozen Mangoes
Now, we need to find the selling price for one dozen mangoes (12 mangoes). Since the selling price of one mango is Rs. 1:

Selling price for one dozen mangoes = 12 * 1 = Rs. 12

Final Answer:
The selling price of one dozen mangoes is Rs. 12.
