Question

if 24z is a multiple of 3, where z is a digit, what is the value of z?​

Answer 1

Answer:

z may be 0,3,6,etc...

Step-by-step explanation:

As mentioned in the question that 24z is a multiple of 3, it means that 3 divide 24z completely.

For the divisibility of any number by 3 it is necessary to have the sum of the number divisible by 3.

For Example -

3432 = 3 + 4 + 3 + 2 = 12

here 12 is divisible by 3 so, this 3432 is also completely divisible by 3

Now,

According to question,

24z

here we need to find z

2 + 4 + z = 9

6 + z = 9

z = 3

Hence,

The Number is 243 and the value of z is 0,3,6 etc..

NOTE - The value of z vary ,

If u took the sum 6 then the value of z is

2 + 4 + z = 6

z = 0

The answer is based on that what sum you taken.
