[tex]a+b+c=200\\
a=200- \frac{20}{100} *200=\ \textgreater \ a=200-40=\ \textgreater \ a=160\\
200-160=40\\
b=40- \frac{25}{100} *40=\ \textgreater \ b=40-10=\ \textgreater \ b=30\\
c=200-(160+30)=\ \textgreater \ c=200-190=\ \textgreater \ c=10\\\\
a+b+c=200\ \textless \ =\ \textgreater \ 160+30+10=200\\\\
