Question 1103558
<pre>
Pritam    :    Sarah    :    Emily
   P      :   E+15      :     E
   3      :    6        :     4
</pre>

{{{6/4=(E+15)/E}}}

{{{3/2=(E+15)/E}}}

{{{3E=2(E+15)}}}
{{{3E=2E+30}}}
{{{E=30}}}



Use that to revise the ratio information:
<pre>
Pritam    :    Sarah    :    Emily
   P      :     45      :     30
   3      :    6        :     4
</pre>
More than one way to go for finding P.

{{{P/45=3/6}}}

{{{P/45=1/2}}}

{{{P=45/2}}}

{{{highlight(P=22.50)}}}
