The ratio of cost price and marked price of an article is 2:3 and ratio of percentage profit and percentage discount is 3:2 . what is the discount percentage?

     CP : MP = 2x : 3x

 => Profit = x

( %) profit : (%) discount = 3:2

Let  CP = 2000,  SP = 300

But   $\frac{3x}{100}\times 200 + \frac{2x}{100}\times 300 = 100$

=>  x = 8.33%

Discount 2x = 16.66%
