Question 1000587
Try it this way:
<i>THREE HUNDRED chocolates are distributed  equally among  certain group of students<b>.</b>   If there are 10 more students, 60 more chocolates  would have been required<b>.</b>  What is original number of students ?</i>


Let the original number of students be the quantity, p.
Chocalates per student originally is {{{300/p}}}.


The hypothetical 10 more students requiring the assumed same ratio of chocolates per student:
{{{(300+60)/(p+10)}}}
should be the same as
{{{300/p}}}.


{{{highlight_green((300+60)/(p+10)=300/p)}}}.
That would be most of what you want to be able to arrange.  After this, only the algebra steps to solve for p is needed.
