A utensil store is offering a 35% discount on the cooker with an MRP ₹1800. What is the selling price? If the cost price was ₹900, what is the percentage profit made after the sale?

The Marked Retail Price (MRP) is ₹1800.
The discount offered is 35%.

$$\text{Discount amount} = 35\% \times 1800$$ $$\text{Discount amount} = \frac{35}{100} \times 1800$$ $$\text{Discount amount} = 0.35 \times 1800$$ $$\text{Discount amount} = 630$$

The discount amount is ₹630.

The selling price is the MRP minus the discount amount.

$$\text{SP} = \text{MRP} - \text{Discount amount}$$ $$\text{SP} = 1800 - 630$$ $$\text{SP} = 1170$$

The selling price is ₹1170.

The cost price (CP) is ₹900.
The profit is the selling price minus the cost price.

$$\text{Profit} = \text{SP} - \text{CP}$$ $$\text{Profit} = 1170 - 900$$ $$\text{Profit} = 270$$

The profit made is ₹270.

The percentage profit is the profit divided by the cost price, multiplied by 100%.

$$\text{Percentage Profit} = \frac{\text{Profit}}{\text{CP}} \times 100\%$$ $$\text{Percentage Profit} = \frac{270}{900} \times 100\%$$ $$\text{Percentage Profit} = 0.3 \times 100\%$$ $$\text{Percentage Profit} = 30\%$$

The selling price is $\boxed{\text{₹}1170}$ and the percentage profit made after the sale is $\boxed{30\%}$.
