Three chickens weighed in pairs 
20150901 

From Shelly: My son brought home a problem of 3 chickens of different weights listing their weights in different groupings of 2. We are to determine the weight of all three together. I think it's a ratio problem, but I am too far removed to formulate a plan to teach him how to solve it. Answered by Robert Dawson and Penny Nom.

Chickens and cows 
20070208 

From Norman: My grandson is testing me on a question he recently solved.
The question is "A farmer has cows and chickens  there are 252 heads and 81 legs  how many of each animal does he have?"
I immediately thought of the quadratic equations I learned 50 years ago at school, but cannot remember how to do it. It is further complicated by the fact that 1 animal must have 3 legs as the total number of legs is 81 (or perhaps he his trying to catch me out) Any helpful advice would be welcome.
Many thanks Norman Answered by Stephen La Rocque and Penny Nom.
