let value of pen = p
so @ 20% discount = 0.8p
and for 10 pens value would be 0.8p*10 = 8p
since customer is getting 12 pens so price per pen = 8p/12
now the cost price is 20 % profit or say 1.2 x
8p/12= 1.2x
p= 1.8x
IMO B

Say the listed price is "p". The customer gets a 20% discount, so each pen costs 0.8p. But the customer is also getting 20% more pens than he is paying for (he gets 2 free when he buys 10). So he is really paying 0.8p for 1.2 pens (20% more than 1), and the cost per pen to him is 0.8p/1.2 = 2p/3.

Now we know this is still 20% greater than the cost of each pen to the seller. Let's call that cost price "c". Then we know the discounted price is 1.2 times c, or 6/5 of c, so we have

2p/3 = 6c/5
p = (3/2)(6c/5)
p = 18c/10 = 1.8c

Let the selling price be s.
The selling price of 10 pens even after discounting by 20%=cost of 12 pens and profit of 20%
=>10*0.8s=1.2*12x
=>s=$$\frac{14.4x}{8}$$ = 1.8x.

Please hit +1 Kudos if you liked the explanation.
