Question

Is x divisible by 2?

1) x divided by 5 gives an odd remainder

2) x divided by 10 gives an odd remainder

bozo190101 · Answer

Believe it should be B. 

1. x/5 can give 1,3,7,9 etc. 

x= 5(Y+1/2/3) 
Depending on whether is Y is odd or even x is divisible by 2. 

Not sufficient

2. x=10(Y+1/2/3) 

Any number when multiplied by 10 will be divisible by 2. 

Sufficient

Rupstar · Answer

How can 1) be sufficient?
7/5= remainder of 2
8/5= remainder of 3
12/5=remainder of 2
13/5= remainder of 3
 hence we cannot ditermine whether the number is odd or even

claudine2005 · Answer

I think it's (B).

1) x divided by 5 gives an odd remainder

That is, x = 5*y + odd number.
If y = 1, then x = 5 + 1 (divisible by 2)
If y = 2, then x = 10 + 1 (not divisible by 2)

2) x divided by 10 gives an odd remainder

That is, x = 10*y + odd number.
If y = 1, then x = 10 + 1 (not divisible by 2)
If y = 2, then x = 20 + 1 (not divisible by 2)

Besides, 10 is even and if x/10 leaves an odd remainder, then x is not divisible by 2 anyway.
