Question: Choose 1 ; if the question can be answered by using one of the statements alone, but cannot be answered using the other statement alone.
Choose 2 ; if the question can be answered by using either statement alone.
Choose 3 ; if the question can be answered by using both statements together, but cannot be answered using either statement alone.
Choose 4 ; if the question cannot be answered even by using both statements together.
What are the values of m and n?
n is an even integer, m is an odd integer, and m is greater than n.
Product of m and n is 30.
Statement A doesn’t provide any specific values of m and n.
∴ Statement A alone is not sufficient to answer the question.
We cannot say what the values of m and n are.
∴ Statement B alone is also not sufficient to answer the question.
If we combine both the statements A and B together, then we have only one possibility m = 15 and n = 2
∴ We have answered the question using both the statements A and B together.
Hence, option (c).
Note: Negative integers are not considered as Even or Odd.
