At an Electronic Data processing unit, five out of the eight program sets P,Q,R,S,T,U,V and W are to be operated daily. On any one day, except for the first day of a month, only three of the program sets must be the ones that were operated on the previous day. The program operating must also satisfy the following conditions: 1. If program P is to be operated on a day, V can’t be operated on that day. 2. If Q is to be operated on a day, T must be one of the programs to be operated after Q. 3. If R is to be operated on a day, V must be one of the programs to be operated after R. 4. The last program to be operated on any day must be either S or U. If the program sets R and W are to be operated on the first day, which of the following could be the other program on that day?

Pipes P and Q fill a cistern in 12 minutes when operated together, Q and R fill it in 20 minutes when operated together and P and R fill it in 15 minutes when operated together. In how many minutes can all 3 pipes fill the cistern if operated together?
Find the average gate power dissipation (Pgav) when the maximum allowable gate power dissipation (Pgm) = 10 kW, with a duty cycle = 50 %.
Consider the following statements. 1. BJT is a current controlled device whereas IGBT is a voltage-controlled device. 2. BJT and IGBT have low input impedance whereas PMOSFET has higher input impedance. 3. IGBTs are available at higher voltage ratings than PMOSFETs because of increment in ON state voltage drop is less in IGBT. 4. IGBT and PMOSFETs have different substrate structures. The correct statements are
Which one of the following equations most directly determines the power dissipation of a resistance when you know the power dissipation of a resistance when you know the voltage drop and current?
Given below are six sentences, four of which (P,Q,R,S) are jumbled. Pick the option that gives the correct order of P,Q,R,S. S-1 We have started manufacturing a new type of cleaning device called 'Neo-clean' for all electronic gadgets. P - It comes with three nozzles to clean the even surface, wedges, and the uneven surface like the keyboard of a computer. Q - By pressing a button with the thumb a vacuum is formed and the dust is sucked in when it is swirled over the gadget. R - The operation of the device is very simple S - It is a small, hand-operated device. S-6 The greatest advantage is that it consumes very little electricity and automatically changes to the battery mode in case of power failure
