Part A is produced on machine $1$ and then processed on machine $2.$ Part B is produced on machine $3.$ One units of part A and two units of part B are assembled on work station $4.$ After that the assembled product will go through station $5$ for final finishing before it is sent out. The final finishing success rate is high as $99\%.$ However, the assembly process is not stable as the success rate is only $92\%.$ The scrap factors of machine $1$ and $2$ are $2\%$ and $3\%,$ and the output of machine $3$ has a defective rate of $4\%.$ The demand of the final product is $300$ per day. Calculate how many of product A and B should be the input of machine $1$ and $3.$
