step by step explain​

Answer 1

answer

Cost = 1900

Step-by-step explanation:

a bag is sold at 1500 ( at loss) and 2100 (at profit)

The loss is twice the profit

Let the profit be ‘x’

So, loss will be '2x'

Now, Selling Price = Cost - Loss or

Cost = Selling Price + Loss

and Selling Price = Cost + Profit or

Cost = Selling Price - Profit

In case of Loss,

Cost = Selling Price + Loss

Cost = 1500 + 2x

In case of Profit,

Cost = Selling Price - Profit

Cost = 2100 - x

Combining both the equations we get

1500+ 2x = 2100- x

3x = 2100 – 1500

3x = 600

x = 200

Profit = 200

Cost = Selling Price - Profit

Cost = 2100 - 200

Cost = 1900
