Mohit sold an article for $24000. Had he offered a discount of 10% on the selling price, he would have earned a profit of 8%. What is the cost price of the article?	Select the correct option:  A) 16000  B) 20000  C) 15000  D) 18000  E) 17000
Let the CP be $x.   Had he offered 10% discount, profit = 8%   Profit = 8/100 x and hence his SP = x + 8/100 x = $1.08x = 20000 - 10/100(20000) = 20000 - 2000 = $21600   =&gt; 1.08x = 21600   =&gt; x = 20000   20000
