Question

if
abc4d is divisible by 4 what cannot be the value of d​

Answer 1

Step-by-step explanation:

Since abc4d is divisible by 4 and as per the divisibilty rule of 4 says that "If the last two digits of a number are divisible by 4 or are 00, then the number is also divisible by 4".

Here we just need to check whether 4d is divisible by 4.

Hence, in order to divide 4d by 4, the possible value of d can be 0,4 and 8.Because 40,44 and 48 are divisible by 4.

Hence, the possible value of d will be 0,4 and 8.

Answer 2

Answer:  The value of d cannot be 0, 4 or 8.

Step-by-step explanation:

For a number to be divisible by 4, the last two digits should either be two zeros (00) or a number that would be divisible by 4.

We have been given abc4d as the number,

For this number to be divisible by 4,

Case 1:

The last two digits of the number  should have been 00

which is not the case.

Case 2:

The last two digits should be a number divisible by 4

The second last digit is given as 4.

Hence, the last digit that is d can now be only 0,4, or 8.

Since 40,44 and 48 will only be the numbers divisible by 4.
