The sum of two numbers is 24, and their difference is 6. The numbers are?
- 20 and 4
- 12 and 6
- 15 and 9
- None of these
Explanation
Let's say the two numbers are x and y.
Given:
x + y = 24 ... (1)
x - y = 6 ... (2)
Adding (1) and (2):
2x = 30
x = 15
Substituting x in (1):
15 + y = 24
y = 9
The numbers are 15 and 9.
