Question

Number of permutations that can be made using all the letters of the word MATRIX is

  1. 120    
  2. 240    
  3. 480    
  4. 720    

Hint:

Basically Permutation is an arrangement of objects in a particular way or order. While dealing with permutation one should concern about the selection as well as arrangement.
In Short, ordering is very much essential in permutations. In other words, the permutation is considered as an ordered combination.

The correct answer is: 720


    The word MATRIX is a 6 letter word
    Thus, number of permutations that can be made using all the letters of the word MATRIX is 6! = 720

    The number of different signals that can be made by 5 flags from 8 flags of different colours is :

     Detailed solution
    We have been told that there are 8flags of different colours by taking 5flags at a time. Thus the total number of flags n=8and flags to be taken at a time r=5
    By applying the permutation formula  = P presuperscript n subscript r space equals space P presuperscript 8 subscript 5 space equals space fraction numerator 8 factorial over denominator left parenthesis 8 minus 5 right parenthesis factorial end fraction space equals space 6720

    Thus, the number of different signals that can be made by 5 flags from 8 flags of different colours is 6720.
