If the production cost in a certain company for first 1 lac item is Rs 20 lac and thereafter Rs 10 for each item. What is the minimum numbers of items that must be manufactured in order to get a cost of Rs 15 per item ?

• If x lac items are to be manufactured , then
  15x = 20+(10*(x-1)
  x= 2
  
  so 2 lac items must be manufactured in order to get a cost of Rs 15 per item .

• let x be number of items made in addition to first 1 lakh items.
  15(10^5 + x)=20*10^5 +10x
  5x=5*10^5
  x=10^5
  ie 1 lakh+1 lakh =2 lakh items are to be manufactured totally.
