Each piece of Model $B$ requires $12$ labour hours for fabricating and $3$ labour hours for finishing. For fabricating and finishing,the maximum labour hours available are $180$ and $30$ respectively. The company makes a profit of Rs $8000$ on each piece of model $A$ and Rs $12000$ on each piece of Model $B$. How many pieces of Model $A$ and Model $B$ should be manufactured per week to realise a maximum profit? What is the maximum profit per week?

  • A
    $12$ pieces of $A$,$6$ pieces of $B$; Max Profit = Rs $1,68,000$
  • B
    $6$ pieces of $A$,$12$ pieces of $B$; Max Profit = Rs $1,68,000$
  • C
    $10$ pieces of $A$,$10$ pieces of $B$; Max Profit = Rs $2,00,000$
