Question

test the divisibility of the following numbers by 11 a 5335 b 9020814 ​

Answer 1

Step-by-step explanation:

a) We have the difference between the sum of digits at odd places (from the right) and the sum of digits at even places (from the right) of a number 5335 is (5 + 3) – (3 + 5) = 8 – 8 = 0, which is divisible by 11. ∴ 5335 is divisible by 11. (b) We have the difference between the sum of digits at odd places (from the right) and the sum of digits at even places (from the right) of the number 9020814 is (4 + 8 + 2 + 9) – (1 + 0 + 0) = 23 – 1 = 22, which is divisible by 11. ∴ 9020814 is divisible by 11.Read more on Sarthaks.com - https://www.sarthaks.com/764961/test-the-divisibility-of-following-numbers-by-11-a-5335-b-9020814
