Question

If 1m3m6 is divisible by 11 then find the value of m​

Answer 1

Answer:

According to divisibility of 11

Sum of odd place digit - Sum of even place digit is divisible by 11.

=> ( 7 + 4 +8 + 6) - ( m +2 + 7 + m) = 0

=> 25 - 2m - 9 = 0

=> 16 - 2m = 0

=> 16 = 2m

=> m = 8

For other numbers except 0, the value of m is greater than 10 that is not possible.

So, m = 8

Answer 2

Answer:

m=5

Step-by-step explanation:

according to divisibility of 11:

Sum of even place - sum of odd place= multiple of 11

so,

1+3+6-(m+m)=0,11,22...

10-2m=0,11...

Case 1

10-2m=0

-2m=0-10

-2m=-10

Negative sign would be cut

2m=10

m=5

Case 2

The answer is not possible as answer will be negative.
