Question 1143654
.


There is some mistake in the problem formulation.


Indeed, it says 

<pre>
    "The ratio of AB to BC and BC to CD is 13/17."
</pre>

It assumes &nbsp;TWO &nbsp;VALUES&nbsp; for the &nbsp;TWO &nbsp;RATIOS, &nbsp;but the problem gives only &nbsp;ONE &nbsp;value.


Did you miss one value ?


Please clarify . . .
