# Thread: the old ship

1. ## the old ship

Some years back I was travelling by a cargo ship from New Zealand to Tahiti. I was curious to look around the ship one day,and in the boiler room I asked a man how old the ship was. He smiled and replied in this way: The ship is twice as old as its boiler was when the ship was as old as the boiler is now. And the combined age of the ship and the boiler is thirty years.' Can you figure out what is the age of the ship and of the boiler?
explain in detail

Age of the ship is 18 and boilder is 12.

Solution:

Assume boilers current age is a.

As per "The ship is twice as old as its boiler was when the ship was as old as the boiler is now"... when ship's age was a boilers age was a/2. Hence difference between their age is a/2. Hence current age of ship is a+a/2

a+a/2+ a =30 => a=12
