x is the 9 digit largest number(digits are 1 to 9 with out repeat) which is divisible by 11 and y second largest number which also divisible by 11 then difference between x and y is?  Choose the correct choice from the following: A) 160 B) 170 C) 188 D) 198 E) 208
"sum of digit at even place and sum of digit at odd places must be adjusted such that their difference is 0 or divisible by 11.   we have 9 digit without repetition,   so sum of digit from 1 to 9 =45   Let sum of digit at odd place will be 'w' and sum of even place will be 'Z'.   W + Z= 45   W - Z = 11   2W = 56   So W = 28 and Z = 17   now the digits at odd place are 2, 4, 6, 7, 9   sum of digit at odd place is   2+4+6+7+9=

28   the digits at even place are 1,3,5,8   sum of digits at even place is  1+3+5+8=

17   so the largest no will be find by put no. of odd and even places in increasing order accordingly   1st lasrgest no is 987563412   and 2nd largest no is 987563214   diference between them   X-Y=198   ANSWER:198
<result>D</result>
