Four liquids are described in the table below. Use the second column of the table to explain the order of their freezing points, and the third column to explain the order of their boiling points.

For example, select '1' in the second column next to the liquid with the lowest freezing point. Select '2' in the second column next to the liquid with the next higher freezing point, and so on. In the third column, select '1' next to the liquid with the lowest boiling point, '2' next to the liquid with the next higher boiling point, and so on.

Note: the density of water is /1.00gmL .

1. A manufacturing company is engaged in producing three types of products;A, B & C. the production department produces each day components sufficient of make 50 units of A. 25 units of B and 30 units of C. the management confronted with the problem of optimizing the daily production of products in assembly department where only 100 man-hour are available daily to assemble the products the following additional information are

Type of product         Profit contribution per unit              Assemble time per product

A                                              12                                              0.8
