Osmotic pressure controlled systems work on the principle of osmotic pressure releasing the drug at constant 1st order kinetics.

Osmotic pressure controlled systems work on the principle of osmotic pressure releasing the drug at constant 1st order kinetics. Correct Answer False

Osmotic pressure controlled systems are formulated such that they release the drug constantly at a zero order rate. The core comprises of the drug and an osmotically active substance such as potassium chloride or mannitol which will be surrounded by a rigid semipermeable membrane coating such as ester or cellulose ester.

Railway fares of 1st, 2nd and 3rd classes between two stations were in the ratio of 8 : 6 : 3. The fares of 1st and 2nd class were subsequently reduced by $$\frac{1}{6}$$ and $$\frac{1}{12}$$ respectively. If during a year the ratio between the passengers of 1st, 2nd and 3rd classes was 9 : 12 : 26 and the total amount collected by the sale of tickets was Rs. 1088, then find the collection from the passengers of 1st class.
