If the difference between the sum of digits in odd places and sum of digits in even places of a number is a multiple of 11 or equal to zero ,then the given number is divisible by 11.

 1 ) Given \: number \: 530664.

 i) Sum \: of \: the \: digits \: at \: odd \: places

 (from \: left ) = 5+0+6 = 11

 ii) Sum \: of \: the \: digits \: at \: even \: places

 (from \: left ) = 3+6+4 = 13

iii) Difference = 13 - 11

 = 2

 \red{ \therefore The \: number \: 530664 \: is \: not \: divisible \: by \: 11 }

 2 ) Given \: number \: 53063.

 i) Sum \: of \: the \: digits \: at \: odd \: places

 (from \: left ) = 5+0+3 = 8

 ii) Sum \: of \: the \: digits \: at \: even \: places

 (from \: left ) = 3+6 = 9

iii) Difference = 9-8

 = 1

 \blue{ ( Which \: is \: not \: divisible \: by\:11 ) }

 \red{ \therefore The \: number \: 53063 \: is \: not \: divisible \: by \: 11 }

 3) Given \: number \: 53067.

 i) Sum \: of \: the \: digits \: at \: odd \: places

 (from \: left ) = 5+0+7 = 12

 ii) Sum \: of \: the \: digits \: at \: even \: places

 (from \: left ) = 3+6= 9

iii) Difference = 12 - 9

 = 3

 \blue{ ( Which \: is \: not \: divisible \: by\:11 ) }

 \red{ \therefore The \: number \: 53067 \: is \: not \: divisible \: by \: 11 }

 4 ) Given \: number \: 53061

 i) Sum \: of \: the \: digits \: at \: odd \: places

 (from \: left ) = 5+0+1 = 6

 ii) Sum \: of \: the \: digits \: at \: even \: places

 (from \: left ) = 3+6= 9

iii) Difference = 9-6

 = 3

 \blue{ ( Which \: is \: not \: divisible \: by\:11 ) }

 \red{ \therefore The \: number \: 53061\: is \: not \: divisible \: by \: 11 }
