Using the multiples of 5 and 6, it is found that she will be 25 years old next year.
What are the multiples of 5 and 6?
They are given as follows, considering numbers less than 40:
- M(5) = {0, 5, 10, 15, 02, 25, 30, 35}.
- M(6) = {0, 6, 12, 18, 24, 30, 36}.
This year, her age is a multiple of 6. Next year, her age will be a multiple of 5, hence, her age next year is a multiple of 5, whose predecessor is a multiple of 6, hence the only option is that she will be 25 years old next year.
