.
Leo's income is 25% more than Jack's.What percent is Jack's income less than Leo's
~~~~~~~~~~~~~~~~~~~


<pre>
The statement "Leo's income is 25% more than Jack's" means that

    L = 1.25*J.


It implies that 

    J = {{{L/1.25}}} = {{{L/((5/4))}}} = {{{(4/5)*L}}} = 0.8*L.


In other words, Jack's income is 80% of Leo's income.


Or, which is the same, Jack's income is 20% less than Leo's income.
