Question

If 1051x85 is divisible by 11 , then find the least value of x .​

Answer 1

Step-by-step explanation:

We know that,

For a number to be divisible by 11 :( the sum of the digits in odd places) - (the sum of the digits in even places) should be a multiple of 11 .

Here no. = 1051x85

Sum of odd places = (1+5+x+5)= (11+x)

Sum of even places = (0+1+8) = (9)

(11+x) - (9)= 11

x=9

The no. will be 1051985

Answer 2

Step-by-step explanation:

We know that ,

For a number to be divisible by 11 ( the sum of the digits in odd places ) - ( the sum of the digits in even places ) should be a multiple of 11

Here no. = 1051×85

Sum of odd places =( 1+5+x+5) = ( 11+x)

Sum of even places = ( 0+1+8 ) =( 9 )

( 11+x) - (9) x = 11

x = 9

The number will be 1051985
