Question 18
The original languages give different age problems. Solve both.
(a) English source: Grandfather and Jane’s ages total 66 now. Three years later, Grandfather will be 8 times Jane’s age. How old is Jane now?
(b) Vietnamese source: Grandfather and Jane’s ages total 69 now. Three years ago, Grandfather was 8 times Jane’s age. How old is Jane now?
Enter (a); (b).
The source languages disagree on both the total age and the time direction. Answer the two variants separately; neither is silently corrected.
