as you can see in the row ages {{{51 -75}}}, total is {{{34}}}, merengue dancers {{{x}}}% will be 

{{{x=34-(10+5+7)=12}}}

then total in first column is {{{22}}}%

then samba column total will be {{{100-(22+32+17)=29}}}%

now you can find  percentage of the members are ages {{{31-50}}} and most recently danced the samba, it will be {{{29-(5+11)=13}}}


same way you can fill out the table and it will be

.......{{{ages}}}......|{{{merengue}}}| {{{bachata}}} | {{{samba}}} | {{{pasillo}}} | {{{total}}}
______________________________________________________________
{{{18-30}}}..........|.... {{{3}}}%          | ....   {{{18}}}%    |....   {{{11}}}%   |.......   {{{ 9}}}%     |....... {{{ 41}}}%
{{{31-50}}}..........|....{{{ 7}}}%          | .......  {{{ 4}}}%      | ......  {{{13}}}%   |......   {{{ 1}}}%     | ...... {{{25}}}%
{{{51-75}}}..........|.. {{{12}}}%        |....  {{{  10}}}%    |....  {{{5}}}%     | ......{{{  7}}}%     |.........{{{ 34}}}%
{{{total}}}............| .. {{{22}}}%        | ....  {{{ 32}}}%    |....  {{{ 29}}}%   |....  {{{  17}}}%   |....  {{{100}}}%

 
so, answer is: {{{13}}}% of the members are ages {{{31}}} to {{{50 }}}and most recently danced the samba
