Three solutions were presented at that link:


&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;one by @josgarithmetic - incorrect &nbsp;(he erased it later);


&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Other by me - very similar to that displayed in the post by &nbsp;@Math_helper, &nbsp;and explained in all details;


&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;and the third by &nbsp;@MathTherapy - even better than my, &nbsp;because it was shorter.
