Question 1125999
----
The ages of A and B are in the ratio 4 : 3. In eight years time the ratio of
their ages will be 9 : 7. Find their present ages. 
----


Now, age of A is 4x; age of B is 3x.


In 8 more years,  {{{(4x+8)/(3x+8)=9/7}}}

{{{9(3x+8)=7(4x+8)}}}

{{{27x+72=28x+56}}}

{{{72-56=x}}}

{{{x=16}}}


Ages NOW, should be  
A, {{{4*16=highlight(64)}}}
B, {{{3*16=highlight(48)}}}
