The ABC Printing Company is facing a tight financial squeeze and is attempting to cut costs wherever possible. At present it has only one printing contract and, luckily, the book is selling well in both the hardcover and paperback editions.

It has just received a request to print more copies of this book in either the hardcover or paperback form. Printing cost for hardcover books is Rs. 600 per 100 while printing cost for paperback is only Rs. 500 per 100. Although the company is attempting to economise, it does not wish to lay off any employees.

Therefore, it feels obliged to run its two printing presses at least 80 and 60 hours per week, respectively. Press 1 can produce 100 hardcover books in 2 hours or 100 paperback books in 1 hour. Press II can produce 100 hardcover books in 1 hour or 100 paperback books in 2 hours.

Determine how many books of each type
