Hi
Arthur and Sam shared some  cards. If Arthur gave 20 to Sam they would have the same number of cards. 
If Sam gave Arthur 10 cards the ratio of cards Arthur had to Sam is 2 to 1. How many cards did Arthur have at the end.

My sons answer is 110 the textbook is 120.

Thanks

The question is posed &amp;nbsp;INCORRECTLY &amp;nbsp;in this problem.



They really &amp;nbsp;DID &amp;nbsp;NOT &amp;nbsp;make any change/exchange.



All their changes/exchanges, &amp;nbsp;described in the problem, &amp;nbsp;were &amp;nbsp;VIRTUAL, &amp;nbsp;&amp;nbsp;NOT &amp;nbsp;real.



So, &amp;nbsp;it &amp;nbsp;MAKES &amp;nbsp;no &amp;nbsp;SENSE &amp;nbsp;to ask &amp;nbsp;&amp;nbsp;&quot; how many cards did &amp;nbsp;Artur have at the end &quot;.



The only question which &amp;nbsp;MAKES &amp;nbsp;SENSE &amp;nbsp;is &amp;nbsp;&amp;nbsp;&quot; how many cards does Artur have ?&quot;



I can not believe, &amp;nbsp;that a peer edited/reviewed textbook may have such &amp;nbsp;FAULTY &amp;nbsp;posed problem.

Do not forget to post your &amp;nbsp;&quot; THANKS &quot; &amp;nbsp;to me for my attentive reading and pointing you &amp;nbsp;NONSENSE &amp;nbsp;in this so called &amp;nbsp;&quot; problem &quot;. 



&lt;U&gt;It is clear and it is &amp;nbsp;OBVIOUS &amp;nbsp;to me&lt;/U&gt; &amp;nbsp;that  &lt;/U&gt;the  &amp;nbsp;&amp;nbsp;&quot; problem &quot; &amp;nbsp;&amp;nbsp;is recovered from a &amp;nbsp;GARBAGE &amp;nbsp;BIN &amp;nbsp;source.
