Ages of Three Children puzzle
The Ages of Three Children puzzle is a logic puzzle which on first inspection seems to have insufficient information to solve, but which rewards those who persist and examine the puzzle critically.
==The puzzle==
A census taker approaches a woman leaning on her gate and asks about her children. She says, "I have three children and the product of their ages is seventy–two. The sum of their ages is the number on this gate." The census taker does some calculation and claims not to have enough information. The woman enters her house, but before slamming the door tells the census taker, "I have to see to my eldest child who is in bed with measles." The census taker departs, satisfied.
The problem can be formatted in myriad ways, presenting the same basic issue; the sum, factor, and that the ages are distinct, such as their ages adding up to today's date, or the eldest being good at chess.
Another version of the puzzle gives the age product as thirty–six, which leads to a different set of ages for the children.
