A woodcutter needs four hours to cut a trunk in three parts. How long will it take to cut a trunk of the same thickness in six parts?
Yesterday I bought a pair of troursers for 150€ (without taxes). The taxes in Spain are 21%. Fortunately, in the shop there are sales and on trousers they have a 21% of discount.
Will I pay finally 150€ for my new pair of troursers?
