?

<pre>
         PAY RATE    TIME      EARNED

Ahmed     200          a        200a

Manu      250          m        250m

TOTAL                            3900


in total, Manu earned Rs. 1100 more than Ahmed,
{{{250m-200a=1100}}}
</pre>

Simplify and solve the system:
{{{system(200a+250m=3900,250m-200a=1100)}}}


You should be able to find a system,  {{{system(4a+5m=78,-4a+5m=22)}}}, ready for easy solving using Elimination Method.
