Second meeting in Vratsa , Bułgaria 27 – 31 Maj 2012

When asked about his birthday, Fryderyk Chopin said:

"The day before yesterday I was only 25 and next year I will turn 27."

This is true only one day in a year - when was he born?

He was born on December 31st and spoke about it on January 1st.

A Polish village is famous for best chickens and hens in the world!

If one and a half hens lay one and a half eggs in one and a half days, how many eggs does one hen lay in one day?

Find the daily rate per hen:

Hens × Days × (Daily Rate) = Eggs

1 ½ × 1 ½ × (Daily Rate) = 1 ½

(Daily Rate) = 1 ½ / (1 ½ × 1 ½)

Daily Rate = 1/(1 ½) = 2/3

So 1 hen in 1 day will lay two-thirds of an egg
