Question

Test the divisibility of number
by 11. 503111214 solve​

Answer 1

Add the odd position digits of the number
i.e. 4+2+1+3+5 = 15

Now add even positioned digits of the number
i.e. 1+1+1 = 3

Subtract sum of odd positioned digits - even positioned digits
= 15 - 3
= 12

Hence the number is not divisible by 11

Answer 2

1 2 3456 7 8 9

503111214

So, first add the numbers on the odd position

= 5+3+1+2+4 = 15

Now, add the numbers on the even position

= 0+1+1+1 = 3

Finally, difference between the sum of odd and even positions = 15-3=12

Since, 12 is not divisible by 11.

Therefore, 503111214 is not divisible by 11...
