DS Question - 30

If q is a multiple of prime numbers, is q a multiple of r?

1) r is less than 4
2) q = 18

Answer: E

From Statement (1) -- q can be positive and r can be negative.
r can also be a real number but not necessarily an integer.
Hence insufficient.

From Statement (2) -- q = 18.
But r can be negative or can be positive.
r can also be a real number not an integer
Hence insufficient

Taking both statements (1) and (2) together -- Again r can be positive or negative. And again r can also be a real number.
Hence insufficient
