If the following statements are given

(x#y) = x + y- xy
(x*y) = (x + y)/2
i) Find the values of x, y will satisfy this equation (x#y)#(x*y) < (x#y)

ii) Find the values of x, y will satisfy this equation (a*b)#(b*c)< (a#b)*(b*c)

• (x#y)#(x*y) < (x#y);(x+y-xy)+(x+y)/2 - (x+y-xy)(x+y)/2 < x+y-xy;
  (x+y)/2-(x+y-xy)(x+y)/2 < 0;(x+y)/2*(1-x-y+xy);so ovral going tobe negtv when x and y both are negative no. becoz 1-x-y+xy iz going to be positive for all x and y
  but if both r of appst sign then no conclsn can be drawn so"ALL -VE NO."

• (x#y)#(x*y) < (x#y)
  (x+y-xy)+(x+y)/2 - (x+y-xy)(x+y)/2 < x+y-xy
  (x+y)/2-(x+y-xy)(x+y)/2 < 0
  (x+y)/2*(1-(x+y-xy))

• (x#y)#(x*y) < (x#y)
  (x+y-xy)+(x+y)/2 - (x+y-xy)(x+y)/2 < x+y-xy
  (x+y)/2-(x+y-xy)(x+y)/2 < 0
  (x+y)/2*(1-x-y+xy)
