how many 5 digit no. can be formed with digits 1,2,3,4,5,6 that r divisible by 4 n digits are not repeated
Read Solution (Total 6)
-
- 192 ways
To be divisible by 4,last two digits must be divisible by 4
The possible last two digits are
12,16,24,32,36,52,56,64
=> Total 5 digit numbers possible = 8*4! = 8*24 = 192 ways

4 3 2 1 (12,16,24,32,36,52,56,64) - 11 years agoHelpfull: Yes(11) No(6)
- exactly 192
last digit should be 12,16,24,32,36,44,52,56 for all individual combination is 24
then total combination is 24*8=192 - 11 years agoHelpfull: Yes(10) No(3)
- The possible digits for last two positions are 12,16,24,32,36,44,52,56,64.
The no. of ways for the first three positions (we need 5 digit number) will be 24, so we get 24*9=216 ways - 11 years agoHelpfull: Yes(5) No(9)
- to be divisible by 4 ,last two digit must be divisible by4
possible digits are
12,16,24,32,36,52,56,64
as we have to make 5 digit no. then the remaining 3 places can be filled in 4*3*2
total possible no is 4*3*2*8=192 - 11 years agoHelpfull: Yes(1) No(1)
- 216 ways.
- 10 years agoHelpfull: Yes(0) No(10)
