Q.5

A frim makes two products X and Y and has a total production capacity of

9 tons per day, Both X and Y require the same production capacity. The

firm has a permanent contract to supply at least 2 tons of X and at least 3

tons of Y per day to another company. Each ton of X requires 20 machine

hours of production time and each ton of Y requires 50 machine hours of

production time. The daily maximum possible number of machine hours is

360. All of the firm?s output can be sold. The profit made is rs.80 per ton

of X and rs.120 per ton of Y.
