easier to look at the prices in absolute percentage values, using the cost price as the base price, aka cost price is 100% of cost price.
The marked price would be 150% of cost price, and
Discounted price would be 100-40=60% of the marked price,
Making the discounted price (60/100)x150=90% of the cost price.
This means there is a 100-90=10% loss, which question states is 250 dollars. Cost price should therefore be (100/10)x250= 2500 dollars:))
