Question

If a man reduces the selling price of a fan from Rs 400 to 300, his loss increased by 40% . What is the Cost Price of fan ?​

Answer 1

Answer:

Let the C.P. = Rs. x.

Then First loss % = (x−400)/x × 100= (100x−40000)/x %

Second loss % = (x−380)/x × 100= (100x−38000)/x %

Given, (100x−38000)/x − (100x−40000)/ = 40

⇒100x−38000−100x+40000=40x

⇒2000=40x

⇒x=50
