Question

1. A man gains Rs. 15 by selling an article at 10% profit
.
What is the cost price and for what price should he sell it if
he is to make 10% profit on sales​

Answer 1

Answer:

Let the cost price be x.

Therefore, selling price y=1.1x

According to the question

y+10=1.25(0.9x)

⇒1.1x+10=1.125x

⇒0.025x=10

⇒x=10/0.025

⇒x=400

∴ The cost price of the articles =Rs. 400.
