The integers m and p such that 2<m<p and m is not a factor of p. If r is the remainder when p is divided by m, is r>1?
1)the greated common factor of m and p is 2
2)the least common multiple of m and p is 30
The answer of this question is A, but I choose D, because 2) is sufficient:
Under the condition of 2) the possible solution is m=3,p=10 or m=5,p=6 so r=1
Who can explain the ets answer to me? |
