let Q be 1 to 9 digit number without repeating which is divisible by 11.and Qe be the substring of Q then Qe is divisible by 11 what is difference of sum of alternatives in Qe
i)o ii)11 iii)22 iv)33

• check the rule of divisibility by 11 on web....... it says if the difference of alternate digit is a multiple of 11....the number is divisible..... so all of above is answer

• 0
  like 1331
  alernative (1+3)-(3+1)=0
  i think

• In Q. option was...a)i & ii b) ii & iii c)i,ii&iii d)All of the obove
  if 0, then no r 132,264....etc
  11,then no r 924(9+4-2=11),429,935..etc
  22. no--->9182745(5+7+8+9-1-2-4),5472819
  So,0,11,22 R possible
  hence, ans...>c)i,ii&iii

• 11.
  opton is are only one

• the question is just asking the divisibility of 11 in one or the other way
  so the answer is 0(i),11(ii).

• The max difference is obtained by 9081726354
  i.e., (9+8+7+6+5) - (0+1+2+3+4) = 25
  Now, 0,11,22 lie under this umbrella and hence can be easily obtained in substrings
