<span>given:
bull's eye radius= x
width of surrounding rings=y
solution:
Radius of the circle=x+4y
Area of the outermost ring=Area of the circle-Area of the penultimate ring
=Ď€(x+4y)^2-Ď€(x+3y)^2
=Ď€(x^2+8xy+16y^2-x^2-9y^2-6xy)
=Ď€(2xy+7y^2)
hence the area of the outermost ring in terms of x and y is π(2xy+7y^2).</span>
If these are number systems then it will turn out like this 
50 x
-- = ---
100 75
We need to find the value of x.
Cross multiply:-
100x = 75 * 50
Divide both sides by 100
x = (75* 50) / 100
= 75 / 2
