Question

Replace by the smallest digit to make the following numbers divisible by 11 4*3271

Answer 1

Step-by-step explanation:

As ,we know the number is divisible by 11 if its difference of the (sum of even place digit ) and ( sum of odd place digit) is 0 or 11

sum of even place = 3+7=10

sum of odd place=4+2+1=7

difference of even and odd =10-7=3

so, we add 3 in the smallest digit to make it divisible by 11

the number comes after adding 3 is

43274

sum of its even digit is 10

sum of its odd digit is 10

difference of its even and odd digit is 0

so it is divisible by 11

43274/11=3934

Answer 2

As ,we know the number is divisible by 11 if its difference of the (sum of even place digit ) and ( sum of odd place digit) is 0 or 11

sum of even place = 3+7=10

sum of odd place=4+2+1=7

difference of even and odd =10-7=3

so, we add 3 in the smallest digit to make it divisible by 11

the number comes after adding 3 is

43274

sum of its even digit is 10

sum of its odd digit is 10

difference of its even and odd digit is 0

so it is divisible by 11

43274/11=3934
