Two Numbers Are Such That Their Difference, The Sum And The Product Are In The Ratio 1:7:36. Find The Numbers And Explain! :cuss:

Re: Simple Arithmatic  8 Dec, 2009
Approved.

Re: Simple Arithmatic  8 Dec, 2009
x = 12
y = 9 xy = 3 x+y = 21 xy = 108 so xy:x+y:xy => 1:7:36 
Re: Simple Arithmatic  8 Dec, 2009
From the question we can say,
xy x+y xy  =  =  = r 1 7 36 From this we get three equations, x  y = r x + y = 7r xy = 36r By solving these equations, we get the value of r=3, x=12, and y=9. 
Re: Simple Arithmatic  8 Dec, 2009
In the previous post, the first equation should be like this:
[(xy)/1] = [(x+y)/7] = [(xy)/36] = r It didn't display correctly, so I am reposting that equation here.
