What is the value of M and N respectively? If M39048458N is divisible by 8 & 11; Where M & N are single digit integers?

• In order to be divisible by 8, the last three Nos. must be divisible by 8.
  Hence the N must be 4
  Next, the given number should be divisible by 11:
  (M+9+4+4+8) -(3+0+8+5+4)

• I had not done the full solution.
  (M+5)MUST BE DIVISIBLE BY 11
  hence M must be 6
  Hence, M is 6 and N is 4

• m=6
  n=4

• if any number is divisible by 8 then the last three digits of a that number should be divisible by 8 also,
  so, 58N should be divisible by 8.
  in this way we find if N=4 then 584 is divisible by 8.
  so , N=8
  now,if the number is divisible by 11 then the differences of the sum of the digits places at odd and even places should be divisible by 11 ,
  sum of the digits at even places =3+0+8+5+N
  =16+N (N=4)
  =20
  SUM OF THE DIGITS AT ODD PLACES=M+9+4+4+8
  =M+25
  
  
  
  now, (M+25)-20 should be divisible by 11
  i.e. M+5 should be divisible by 11 and M should be a single digit.
  so if M=6 , then M+5 =11 is divisible by 11.
  
  
  Ans. M=6, N=4
