Age Difference Puzzle
How many years ago was the kerosene lamp twice the age of the electric lamp?
A kerosene lamp is 95 years old and an electric lamp is 55 years old.
Final answer: The kerosene lamp was twice the age of the electric lamp 15 years ago. The electric lamp would've been 40 years old then, which is the difference in their current ages.
Answer:
15 years ago, the kerosene lamp was twice the age of the electric lamp.
Let's break down the puzzle about the age difference between the kerosene lamp and the electric lamp. Currently, the kerosene lamp is 95 years old, while the electric lamp is 55 years old. This means there is a 40-year difference in their ages.
When the kerosene lamp was twice the age of the electric lamp, the electric lamp had to be 40 years old (the difference in age between the two lamps). Since the electric lamp is currently 55 years old, this scenario must have happened 15 years ago.
Therefore, 15 years ago, the age of the kerosene lamp was twice the age of the electric lamp. This provides a fun math puzzle to exercise your brain!
