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.
Answer & solution
- A
1
- B
2
3
- D
4
Statement A doesn’t provide any specific values of m and n.
∴ Statement A alone is not sufficient to answer the question.
Using statement B alone:
m × n = 30 = 1 × 30 = 2 × 15 = 3 × 10 = 5 × 6
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.
