Since the sum of 5 consecutive positive multiples of a prime number is 105, the mean is 21.
The numbers whose sum is 105 are 19,20,21,22,23.
Hence the prime number we are looking for is 19.
Now, we need the sum of the first 5 positive multiples of this prime number which is not possible
as the only positive multiples that a prime number has are the prime number and 1.
Since we need sum of first 5 positive multiples of this prime number it cannot be determined(Option E)
