Question 724056
This might be understood if your "totally" means revenue is 22600 of the rs units were sold.


Let x = count of rs.100 tickets
Let y = count of rs.120 tickets

{{{100x+120y=22600}}} and {{{x+y=200}}}.  Solve x and y in that system.


The first equation is simplifiable to 10x+12y=2260, or 5x+6y=1130, so a better system is:
{{{5x+6y=1130}}}
{{{x+y=200}}}
Solve system for x and y.
