Question

how to check the divisibility of 11 for the following numbers:
a) 1996751
b)26004
c)260193
d)602111213​

Answer 1

Answer:

The sun of even digits of subtracted from the sim of the of digits and if this results in 0 or 11 then the number is divisible by 11

1) 1996751

Now add the underlined numbers separately and un-underlined numbers separately

1+9+7+1 = 18

9+6+5 = 20

Now subtract the sum of the underlined or odd numbers and un-underlined numbers or you can say then as even numbers

20-18 = 2

Hence, the number is not divisible by 11 as the answer is neither 11 nor 0

2) 26004

2+0+4 = 6

6+0 = 6

So 6-6 = 0

Hence, this number is divisible by 11

3) 260193

2+0+9 = 11

6+1+3 = 10

11-10 = 1

Hence, the number is not divisible by 11

4) 602111213

6+2+1+2+3 = 14

0+1+1+1 = 3

14-3 = 11

Hence, the number is divisible by 11
