Let’s assume that the age of the ship at present is X years and of the boiler Y years.
Then
The ship X is twice as old as its boiler (Y—X) was when the ship was (x—X) as old as the boiler is now.
X = 2 (Y—X) and (x—X) 2. Eliminating X gives 4Y = 3x. Also, x+Y = 30
Y (the boiler) = 90/7years and
X (the ship)= 120/7 years 5307 views

If I walk 26 steps I require 30 seconds.
If I walk 34 steps I require only 18 seconds. Multiplying the 30 by 34 and 26 by 18 we get 1020 and 468.
The difference between 1020 and 468 is 552. When we divide this number by the difference between 30 and 18, i.e. by 12 we get the answer 46—the number of steps in the stairway. 6118 views
