Question

check whether the following number are divisible by 11 or not 99999​

Answer 1

Answer:

no

Step-by-step explanation:

for divisibility by 11 the difference of the sum of the digits of even and odd places must be 0 or divisible by 11.

let's check

(9+9+9)-(9+9)

which equals 9.

as 9 is neither 0 nor divisible by 11. So, the no. is not

divisible by 11.

Answer 2

Sum of Digits at odd places = 9+9+9= 27

Sum of Digits at even places = 9+9=18

Difference= 27-18 = 9

9 is not divisible by 11

We know thàt if the difference is 0,11,22,33, ...........

Thén the number is divisible by 11

Therefore, 99999 is not divisible by 11
