(Manufacturing problem) A manufacturer has three machines I , II and III installed in his factory. Machines I and II are capable of being operated for at most 12 hours where as machine III must be operated for atleast 5 hours a day. She produces only two items M and N each requiring the use of all the three machines. The number of hours required for producing 1 unit of each of M and N on the three machines are given in the following table: She makes a profit of Rs 600 and Rs 400 on items M and N respectively. How many of each item should she produce so as to maximise her profit assuming that she can swll all the items that she produced ? What will be the maximum profit ?

A student forgot to add the reaction mixture to the round bottomed flask at '27^circ C', but he/she placed the flask on the flame. After a lapse of time, he realised his mistake, using a pyrometer, he found the temperature of the flask was '477^circ C'. What fraction of the air would have been expelled out?
