When a 1-phase transformer is connected in parallel, there are four conditions for proper parallel operation, but when two or 3-phase transformer paralleling is done, there are two additional points along with those four conditions applied for 1-phase. Statement 1 - The phase sequence must be the same. Statement 2 - The phase shift between primary and secondary voltages must be the same for all transformers connected in parallel. From the above two Statements (s), which is/are the correct conditions in this regard?
Election for a constituency was conducted in two phases where three contestants A, B and C contested. In first phase 48% of the total voters voted out which A and B got 32% and 46% of the votes (remaining to C). In the next phase where 75% of the remaining people voted A and B got 43% and 33% of the votes casted (Remaining to C). If the amount of votes obtained by A in phase 1 is less than the total votes obtained by B in phase 1 and C in phase 2 by 16080, then what is the total number of voters in the constituency?
