• B. Product of $m$ and $n$ is $30$
  • A. $1$
  • B. $2$
  • C. $3$
  • D. $4$

Answer 1

I think C is the answer  i.e can be answered uisng both statements.

first one is not sufficient as multiple value of m and n can occur. so one is insufficient .
for the same reason 2 also . multiple value of m and n like 6*5, 5*6, 30*1

both combined  can give answer as only one case is true i.e 15*2 we can be sure about that any other thing does not work , like 6*5, 30*1 . any other combination . so answer is c .
