Question

A msn sold a radio-set for Rs 250and gained one-ninth of it's cost. Find i) its cost prize ii) its profit percent

Answer 1

Hi friend
-------------
Your answer
------------------

Selling price of a radio set = Rs 250

Gain = 1/9 of cost price

i) Cost price
--------------------

Let the cost price be x.

Then,
-----------

Cost price = Selling price - gain

=> x = 250 - x/9

=> x + x/9 = 250

=> 10x/9 = 250

=> x = (250 × 9)/10

=> x = Rs 225


ii) Profit percent
-------------------------

Profit percent = profit/cost price × 100

= (225/9)/225 × 100)%

= (225/9 × 1/225 × 100)%

= 100/9 %

= 1.11 %
