Question

A watch was sold at a loss of 9%. It was observed that if the selling
price was Rs.420/- more then the profit made would have been 5%
What is the actual Cost price of the watch?​

Answer 1

Answer:

2730

Step-by-step explanation:

cost price always = 100 %

9 % loss means selling price = 91 %

if 420 add then 5 % profit  means selling price = 105 %

it means 105 % - 91 % =420  ==> 14 % =420

so 91 % ( actual cost price) = (91 * 420) / 14 = 2730
