<PRE><B>Question 1149441</B>
&lt;br&gt;
Given the ratio A:B:C = 5:3:2,&lt;br&gt;
let A = 5x
let B = 3x
let C = 2x&lt;br&gt;
That is one standard method for starting work on a problem where a ratio like that is given.&lt;br&gt;
So we know the difference between A and C is 60:
{{{5x-2x = 60}}}
{{{3x = 60}}}
{{{x = 20}}}&lt;br&gt;
And so&lt;br&gt;
A = 5x = 100
B = 3x = 60
C = 2x= 40&lt;br&gt;
And then the difference between B and C is 60-40 = 20.&lt;br&gt;
