Which of the following numbers is divisible by 11?
1 1011011
2 1111111
3 22222222
4 3333333
Explanation:
22222222 A number is divisible by 11, if the difference of the sum of the digits on even places and odd places is either 0 or divisible by 11. From option (a), we get Sum of the digits at even places = 1 + 1 + 0 = 2 Sum of the digits at odd places = 1 + 0 +1 + 1 = 3 Difference = 3 - 2 = 1 It is not divisible by 11. From option (b), we get Sum of the digits at even places = 1 + 1 + 1 = 3 Sum of the digits at odd places = 1 + 1 + 1 + 1 = 4 Difference = 4 - 3 = 1 It is not divisible by 11. From option (c), we get Sum of the digits at even places = 2 + 2 + 2 + 2 = 8 Sum of the digits at odd places = 2 + 2 + 2 + 2 = 8 Difference = 8 - 8 = 0 It is divisible by 11. From option (d), we get Sum of the digits at even places = 3 + 3 + 3 = 9 Sum of the digits at odd places = 3 + 3 + 3 + 3 = 12 Difference = 12 - 9 = 3 It is not divisible by 11. Hence, 22222222 is divisible by 11.
