Reasoning and answer: In ten years, Jackson will be 20 + 10 = 30 years old. If Jackson is 20 now, Mandy is 20 + 10 = 30 years old. Ten years from now, Mandy will be 30 + 10 = 40 years old. The combined age of Jackson and Mandy ten years from now is 30 + 40 = 70 years. Adele is 3 / 4 times as old as Jackson, meaning she is 3 / 4 * 20 = 15 years old. Adele's age will be 10 + 15 = 25 years old ten years from now. Altogether, Mandy, Jackson, and Adele will have a total of 25 + 70 = 95 years.
The answer: 95
