Answer: There are 819 fewer number of cases of water bottle that all athlete, all coaches and all judges will get.
Explanation:
Since we have given that
Number of days the meeting is going on = 3 days
Number of athletes = 117
Number of coaches = 7
Number of judges = 4
Number of bottles given to each athlete each day = 4
Total number of bottles total athlete for 3 days will get is given by
![117* 4* 3\\\\=1404](https://img.qammunity.org/2020/formulas/mathematics/high-school/bif5mcij651vivkteq1hk8apc0zggxknx4.png)
Number of bottles given to each coach each day = 3
Total number of bottles total coach for 3 days will get is given by
![7* 3* 3\\\\=63](https://img.qammunity.org/2020/formulas/mathematics/high-school/bv7i2inh2gpkf9h95gufijxmjit6l02tp7.png)
Number of bottles given to each judge each day = 2
Total number of bottles total judge for 3 days will get is given by
![4* 3* 2\\\\=24](https://img.qammunity.org/2020/formulas/mathematics/high-school/akkmjfm05veazff4gkj43eogoddxx43ghx.png)
Number of cases of water bottle is given to athletes is given by
![(1404)/(24)](https://img.qammunity.org/2020/formulas/mathematics/high-school/pxgar64dl2tzaxhlqxtv1wmgdyo74urn2x.png)
Number of cases of water bottle is given to coaches is given by
![(63)/(24)](https://img.qammunity.org/2020/formulas/mathematics/high-school/eo43xnflpa78f3b1klpq90ip56i6ocxmlm.png)
Number of cases of water bottle is given to judges is given by
![(24)/(24)](https://img.qammunity.org/2020/formulas/mathematics/high-school/u82eqz6kovd7dsugkz7s2dvxbxa7peid11.png)
We need to find the fewer number of cases that all athlete , all coaches and all judges will get
![\text{L.C.M. of }(1404)/(24),(63)/(24),(24)/(24)\\\\=(L.C.M.\ of\ 1404,63,24)/(H.C.F.\ of\ 24,24,24)\\\\=(19656)/(24)\\\\=819](https://img.qammunity.org/2020/formulas/mathematics/high-school/rep5cxkivly7lo5w35n6b0kg8xl5vl12ih.png)
Hence, there are 819 fewer number of cases of water bottle that all athlete, all coaches and all judges will get.
