(C) $$25.20$$
(D) $$26.25$$
(E) $$28.00$$

so finally he should have 25% profit over $16.8 which is 16.8(1+25/100)=$21
but this $21 is discounted price of SP say x at 25% again x(1-25/100) = 21 thus x=$28

Cost Price + Profit = Selling Price = Marked Price - Discount

Now, here Selling Price will be 16.80*125/100 = 21

Now, at this point we have here , Selling Price which is 75% of Marked Price...

So, Marked Price = 21/0.75

Or, Marked Price = 28.00

Hence Correct answer must be (E) 28

In order to give his customers a 25−percent25−percent discount on the price and still net a 25−percent25−percent profit on the cost of an item, at what price should a merchant mark an item if it cost him $16.80? (A)$21.00
(B) $21.90 (C)$25.20
(D) $26.25 (E)$28.00

Do it in steps:

Given: Cost price : $16.80 Final result to achieve is "to gain 25%" of cost price so keeping end result in mind find the 25% of Cost price =$16.80*(25/100) =$16.80 *(1/4) =$4.20

Now add the profit in the cost price=$16.80+$4.20= $21.00 Now you should use the options that is when you apply discount of 25% on any of the option and if it gives you$21.00 as a result then it is your answer:

if you give the discount of 25 % on $28.00=$28.00 - $28.00 (25/100) =$28.00 -$7.00 =$21.00
