A and B are two positive odd numbers. A × B = 9 and A < B. What is the value of A + B?
Given:
A and B are positive odd numbers.
A × B = 9
A < B
Solution:
Find the pairs of positive numbers that multiply to 9:
1 × 9 = 9
3 × 3 = 9
Since A and B must be positive odd numbers and A < B, the only valid pair is A = 1 and B = 9.
Calculate the value of A + B:
1 + 9 = 10
Final Answer
So the correct answer is (c)
