Answer:
15000 Is the sq in normal inches 
 
        
                    
             
        
        
        
lets take 
x+y=100 firstly. 
then x=100-y equation (i)
Now, 
x-y=10
Putting value of x from equation(i)
100-y-y=10
-2y=10-100
-2y=-90
therefore, y=45
Now, 
putting value of y in equation(i)
we get 
x=100-45
ie x=55
hence, x=55 & y=45
