Question 1136506
<br>
The ratio of their current salaries is 3:5.  Avoid a lot of ugly computations with fractions by letting those salaries be 3x and 5x.  Then<br>
{{{(3x+200)/(5x+200) = 13/21}}}
{{{65x+2600 = 63x+4200}}}
{{{2x = 1600}}}
{{{x = 800}}}<br>
Their current salaries are 3x = 2400 and 5x = 4000.
