What are the conditions to be satisfied by a voltage source for using it in switching regulator. i. It must supply the required output power and the losses associated with the switching regulator ii. It must be large enough to supply sufficient dynamic range line and load variations iii. It must be sufficient high to meet the minimum requirement of the regulator system to be designed iv. It may be required to store energy for a specified amount of time during power failure especially if the system is designed for a computer power supply.

X' agreed to supply 1000 tons of iron at Rs. 100 per ton to 'Y' to be delivered not later than 31st January, 2002. 'X' also entered into a contract with 'A' for purchase of 1000 tons of iron at Rs. 80 per ton telling 'A' clearly that the iron is needed before 31st January, 2002 for supply to 'Y' to fulfil the contract with Y. 'A' fails to supply the iron to 'X' who in tum failed to supply the same to 'Y'. In an action by 'X' against 'A'.
A Time taken by pipe P and Q to fill the tank is 120/23 minutes. Time taken by drain pipe S to empty the tank is 12 minutes more than pipe P to fill the tank. Time taken by pipe Q is 15 minutes. Ratio of time taken by R to fill up the tank and by pipe Q is 4 : 5. What is total time taken to fill the whole tank when all the pipes are open? 
Time taken by pipe A and pipe B to fill up the cistern is 12 minutes whereas time taken by pipe C to empty the whole cistern is twice that of time taken by A and B together to fill the tank and ratio of time taken by pipe A and B to fill up the tank when operating alone is 2 : 3. If pipe A and B are alternatively opened every 6 minutes and C is opened with pipe B but closed when pipe A is opened then calculate total time taken to fill up the whole cistern.
