Question

The number 5A is divisible by 3.

Is it true that A must be divisible by 3?​

Answer 1

Answer:

Yes,

It must be true.

Answer 2

For eg. let's consider A as 6

then 5(6) = 30 is divisible by 3 and 6 too is divisible by 3

and if we take A as 4

then 5(4) = 20 is not divisible by 3 and 4 too is not divisible by 3

therefore for A to be divisible by 3 the condition is that the value of A should be a multiple of 3 to be divisible by 3
