  Galaxy. -----2500
  Sam duo having 33.33% profit so profit is 500

• let cost of duo is x & galaxy is(40000-x).so c.p of duo=133.33x/100
  & c.p of galaxy =80*(40000-x)/100
  now as no profit and loss,
  so 133.33x/100+80*(40000-x)/100=40000
  solving it x=13125.82

• let duo=x,galaxy=y
  x+y=40000
  1.33x+0.8x=40000
  solving 2 eq...we get x=15094
  so x=15000
