The secret to solving an age puzzle is understanding how time affects the relationship between people’s ages. Although everyone gets older, the age difference between two people always stays the same.

For example, imagine Sarah is 10 years older than her brother. If her brother is 15 today, Sarah must be 25. Five years ago, her brother was 10 and Sarah was 20. Their ages changed, but the difference remained exactly 10 years.

This simple principle is the key to solving many confusing age riddles. When a question mentions the past or future, calculate each person’s age at the same point in time before comparing them.

Another useful trick is to work backward. If you know someone’s age in the future, subtract the number of years that will pass to find their present age.

So, how old is Sarah in the original puzzle? Unfortunately, the linked page wasn’t accessible, and I couldn’t verify the exact clues or correct numerical answer. Giving a specific age without seeing the puzzle would only be a guess.

The challenge is a reminder that solving riddles isn’t always about being quick. Sometimes, the smartest approach is to slow down and examine every detail.
