<H3>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Formulation of this problem is &nbsp;LAME.</H3>


It is &nbsp;LAME, &nbsp;because it &nbsp;DOES &nbsp;NOT &nbsp;SAY &nbsp;that the rest of items, &nbsp;13 - 4 - 3 = 6 &nbsp;are from the shop &nbsp;A.


Moreover, &nbsp;the shop &nbsp;A &nbsp;is not mentioned in the problem, &nbsp;at all.



&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Hey, &nbsp;are you &nbsp;OK &nbsp;there, &nbsp;at the opposite side of the &nbsp;Internet, &nbsp;formulating your tasks in this curved way ?




NEVER &nbsp;SAW &nbsp;such &nbsp;LAME &nbsp;formulation . . . 



Who created it ?  &nbsp;&nbsp;Who is the author ?



In such form, &nbsp;your creations are good only for re-cycling . . .

In my understanding, &nbsp;when the tutor sees such a post, &nbsp;there is only one right way to treat it:  


&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;to return it to the visitor for correction.



&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Any other action is WRONG.
