Question

What should be placed in place of x so that 23567x32 will be divisible by 11?​

Answer 1

the divisibility rule of 11 is to first add the numbers of odd and even separately and the subtract the sum of even place numbers from the sum of odd place numbers

so,

odd place numbers=2+5+7+3=17

even place numbers=3+6+ x +2=11+ x

now the result have to be 0 or a multiple of 11 so we can say x to 6 so,then only the answer will be 0

so our final answer is 0

23567632

23567632/11=2142512
