Input Output reasoning-1

In this session problems based on input and output have been discussed. A string of words, letters or numbers are sent to some machines or computers or processors as input and step by step different outputs are obtained. Students have to crack the code and answer the questions. This type of questions are frequently asked in Bank PO, CMAT, XAT and other competitive exams. Problems are generally based on alphabetic arrangement, word shifting and some times mathematical operations are involved.
