If there is a discount of 40% on an article costing Rs 7000, then the price after discount is:

To find the price after a discount of 40%, we need to calculate the discounted amount and subtract it from the original price.

Step 1: Calculate the discount amount
Discount = Percentage Discount * Original Price
Discount = 40% * Rs 7000

To find 40% of a number, multiply the number by 0.40 (which is equivalent to 40/100).
Discount = 0.40 * Rs 7000

Step 2: Calculate the price after discount
Price after discount = Original Price - Discount

Using the values we calculated earlier:
Price after discount = Rs 7000 - Discount

Now, let's calculate the discount and the final price:

Discount = 0.40 * Rs 7000
= Rs 2800

Price after discount = Rs 7000 - Rs 2800
= Rs 4200

Therefore, the price after a discount of 40% on an article costing Rs 7000 is Rs 4200.

(1.00 - .40) * 7000
