How many Numbers can be formed with digits 2,4,6,8 without repetition?
option
i. 124
ii. 256
iii. 64
iv. 84

• Number of one digit numbers = 4
  Number of two digit numbers = 4 P 2 = 12
  Number of Three digit numbers = 4 P 3 = 24
  Number of four digit numbers = 4 P 4 = 24
  
  So, total = 24 + 24 + 12 + 4 = 64
  
  Answer is 64

• see here by using the given digits we can form single digit nos.,2 digit nos.,3digit nos. & 4 digit nos.
  Now,
  Number of 1 digit Numbers = 4
  Number of 2 digit Numbers = 4*3=12
  Number of 3 digit Numbers = 4*3*2=24
  Number of 4 digit Numbers = 4*3*2*1=24
  therefore required result will be = 4+12+24+24=64

• Case1: There are 4 number of 1 digit.
  4 3
  Case2:
  4*3=12
  There are 12 number of 2 digit.
  Case3:
  4 3 2
  4*3*2=24
  There are 24 numbers of 3 digits.
  Case 4:
  4 3 2 1
  There are 24 numbers of 4 digits.
  Hence,the total required numbers=4+12+24+24=64

• number with one digit= 4ways
  number with 2 digits=4*3=12ways
  number with 3 digits=4*3*2=24ways
  number with 4 digits=4*3*2*1=24 ways
  so totao numbers=4+12+24+24=64

• no. of 1 digit numbers possible=4
  no. of 2 digit numbers possible=4*3=12
  no. of 3 digit numbers possible=4*3*2=24
  no. of 4 digit numbers possible=4*3*2*1=24

• Single digit numbers=4
  2digit numbers=12
  3 digit numbers=4*3*2=24
  4 digit number=4*3*2*1=24
  Total=64

• total Number of 1 digit Numbers = 4
  total Number of 2 digit Numbers = 4*3=12
  total Number of 3 digit Numbers = 4*3*2=24
  total Number of 4 digit Numbers = 4*3*2*1=24
  therefore total no. = 4+12+24+24=64

• Number of one digit numbers = 4
  Number of two digit numbers = 4 P 2 = 12
  Number of Three digit numbers = 4 P 3 = 24
  Number of four digit numbers = 4 P 4 = 24
  
  So, total = 24 + 24 + 12 + 4 = 64
