Answer» Correct Answer - Option 3 : 86328 Concept For a number to be divisible by 44, it should be divisible by 4 and 11. Divisibility by 4 : Last two digits of given number should be divisible by 4 Divisibility by 11 : The sum of the digits at even place is subtracted from the sum of the digits at odd places. If the result is either 0 or divisible by 11, then the original number is divisible by 11 Calculation Checking divisibility by 4 : Last two digits of all options are 34, 18, 28 and 08 From the given options, only option 3 and 4 are divisible by 4 since their last two digits are divisible by 4 Now, checking option 3 and 4 for divisibility by 11 : 3) 86328 (8 + 3 + 8) - (6 + 2) = 19 - 8 ⇒ 11, which is divisible by 11 So, option 3 is divisible by 11 4) 86208 (8 + 2 + 8) - (6 + 0) = 12, which is not divisible by 11 Since option 3 is divisible by both 4 and 11, therefore it is divisible by 44. |
