If \(N = 1234@\) and \(@\) represents the units digit of \(N\), is \(N\) a multiple of 5?

(1) \(@!\) is not divisible by 5

(2) \(@\) is divisible by 9


Lets do 3 things first

For N to be divisible by 5 @ has to be 0 or 5

Second 0! = 1

Third: zero is a multiple of every integer (except zero itself)

(1) \(@!\) is not divisible by 5
@!, 0! = 1, when put back in the question, this will make N divisible by 5,, Yes
4! =24,when put back in the question, this will make N divisible by 5, No

(2) \(@\) is divisible by 9[/quote]
m can be 0, this is / by 9, when put back in the question, this will make N divisible by 5, Yes
m can be 9, when put back in the question, this will make N divisible by 5,No

We have the common value from both the statements
0, making N divisible by 5
