  ## Brain teasers to keep minds active The surgeon is the mother If 1.5 hens lay 1.5 eggs in 1.5 days, it must be that one hen would lay one egg in the same time period: 1.5 days. Now, if one hen lays one egg in 1.5 days, it means that one hen would lay only ⅔ of an egg in one day. So the answer is ⅔ of an egg. starting

This is worked out
7 large cartons (7 x 8 = 56 boxes)
4 small cartons (4 x 10 = 40 boxes)
11 cartons - 96 boxes  After 3 socks have been selected, you will have two of the same colour 189

So 6 X 3= (6x3) = 18
(6+3) = 9
=189 ARE 55

To get the result you would add the following number to the last result, 20+5=25, 25+6=31 and so on. So what about the answer? 38+9=47? Well it could be, if the rule was to add the last result to the next number. However, 8 is missing. So if the rule was to add the previous result to the next ascending number, to get the right answer you would have to first solve 38+8=46 and then 46+9=55 C.
