A person inhales to his maximum capacity and then he exhales also to his maximum. Suppose he hold his breath after that maximum expiration for 5 seconds would there be any exchange of respiratory gases occuring in lungs during that period. How?

A person inhales to his maximum capacity and then he exhales also to his maximum. What is the volume of air thus breathed out?

A person inhales to his maximum capacity and then he exhales also to his maximum. a) What term would you use for the volume of air thus breathed out.

In each of the following experiments specify appropriate sample space i) A boy has a 1 rupee coin, a 2 rupee coin and a 5 rupee coin in his pocket. He takes out two coins out of his pocket, one after the other. ii) A person is noting down the number of accidents along a busy highway during a year.

A factory manufactures two types of screws, A and B . Each type of screw requires the two machines, an automatic and a hand operated.It takes 4 minutes on the automatic and 6 minutes on hand operated machines to manufacture a package of screws A, while it takes 6 minutes on automatic and 3 minutes on the hand operated machines to manufacture a package of screws B. Each machine is available for at the most 4 hours on any day. The manufacturer can sell a package of screw A at a profit of Rs 7 and screws B at a profit of Rs 10 . Assuming that he can sell all the screws he manufactures, how many packages of eách type should the factory owner produce in a day in order to maximise his profit? Determine the maximum profit.

A person deals only two items,Cycles and scooters.He has Rs.1,20,000 to invest and a space to store at most 38 pieces.One scooter costs him Rs.12000 and a cycle costs him Rs.800.He can sell a scooter at a profit of Rs.1500 and a cycle at a profit of Rs.200.Assuming that he can sell all the items he buys,how should he invest his money in order that he may maximum his profit.Formulate the problem mathematically.

If a young man rides his motor cycle at 25 k . p . h , he has to spend Rs. 2 per km on petrol, if he rides it at ạ faster speed of 40k.p.h. , the petrol cost increases to Rs. 5 per k m . He has Rs. 100 to spend on petrol and wishes to find what is the maximum distance, he can travel within the hour. Express this as a linear programming problem and then solve it.

A merchant plans to sell twó types of personal computers - a desktop model and a portable model that, will cost Rs 25000 and Rs. 40000 respectively. He estimates that the total monthly demand of computers will not exceed 250 units. Determine the number of units of each type of computers which the merchant should stock to get maximum profit if he does not want to invest more than Rs 70 lakhs and if his profit on the.desktop model is Rs 4500 and on portable model is Rs 5000 .
