Henry Ernest Dudeney/Modern Puzzles/92 - A Cow's Progeny

by : $92$

 * A Cow's Progeny
 * "Supposing," said my friend Farmer Hodge, "that cow of mine to have a she-calf at the age of two years,
 * and supposing she goes on having the like every year,
 * and supposing every one of her young to have a she-calf at the age of two years,
 * and afterwards every year likewise, and so on.
 * Now, how many do you suppose would spring from that cow and all her descendants in the space of twenty-five years?"


 * I understood from Hodge that we are to count from the birth of the original cow,
 * and it is obvious that the family can produce no feminine beef of veal during the period stated.
