what is x+y+z=?

Answer

27

X+Y=10
Y=10-X Use this to substitute for Y
X+Z=20
Z=20-X Use this to substitute for Z.
Y+Z=24 Substitute for Y and Z

A poor farmer went to a market to sell some pea and lentil, however as he had only one sack and didn't want to mix peas and lentils, he poured in the sack the peas at first, bound the sack up and than poured in the lentils. At the market a rich innkeeper wanted to buy the peas, but he did not want the lentils.
How would you solve this problem if you had only the sack of innkeeper, which he wants to keep (without devaluing the goods).

Answer

Pour the lentils into the innkeeper’s sack, bind it and turn inside out. Pour in the peas.
Then unbind the sack a pour the lentils back to your sack.
