Question 1113402
Their present ages may be  x and 2x.


Five years ago, for 1:3,
{{{(x-5)/(2x-5)=1/3}}}

-

{{{3x-15=2x-5}}}

{{{highlight(x=10)}}}-----the younger brother now.


Ratio of ages in 5 more years
{{{(10+5)/(20+5)=15/25=highlight(3/5)}}}




*************WRONG BELOW*****************
Their PRESENT ages are 2 and 4.
--
In five more years, ratio:
{{{cross((2+5)/(4+5)=7/9)}}}
