The current ages of three people in the ratios of 4:7:9. Eight years ago, their combined ages were 56. Determine their current ages (in years).
A. 8, 20, 28 B. 16, 28, 36 C. 20, 35, 45 D. 20, 35, 45
Explanation: Let's say their current ages are 4x, 7x, and 9x years.As a result, (4x - 8) + (7x - 8) + (9x - 8) = 56.20 x 80 =x equals 4.They are 4x = 16 years old, 7x = 28 years old, and 9x = 36 years old, respectively.
