Tanya is 6 times younger than her grandfather. If a zero is placed between the digits of her age, it be the age of her grandfather. How old is Tanya?

Tanya is 10 Years old.

Hello! So Tanya is 6 times younger than her grandfather and with the zero being inserted between her age, that definitely mean that her grandfather is at least 100 years old. Her grandfather is 108 years old, because a zero placed between Tanya's age is 108, which would make Tanya 18 years old, and 18 * 6 is 108. The answer is 18 years.
