Answer 1

question 5
it will be 5*4*3*2*1
as the position 0 zero is fixed and none of the numbers can be repeated

Answer 2

ans 6] we can choose 5 in 5C2 ways = 10 ways 
            we can choose 2 consonants from 21 in 21C2= 210 ways 
            now these selected 4 letters can be arranged in 4 ways!=24 ways 

             by fundamental theorem 
              total number of ways[words] =10.210.24 
                                                                  =50,400
