The cost in taka of manufacturing x microwaves is 6000+300x taka. the amount received when selling these x microwaves is 700x taka. what is the least number of microwaves that must be manufactured and sold so that the net profit is tk 2400?

• net profit=s.p-c.p,, 700x-(300x+6000)=2400, 400x=8400,x=21, so, least no. of microwaves is 21.

• ans :8.4
  sp=700x,cp=6000+300x,profit=2400
  then Gain=sp-cp
  2400=700x-6000+300x
  x=8.4
