Maths Riddles

Some Maths Riddles that you could try so get your thinking caps on (:

1) How can you add eight 8's to get the number 1,000? (only use addition)

2) What weighs more - a pound of iron or a pound of feathers?

3)If you take 3 apples from a group of 5, how many do you have?

4) Why is the longest human nose on record is only 11 inches long?

5) If a rooster laid 13 eggs and the farmer took 8 of them and then another rooster laid 12 eggs and 4 of them were rotten, how many of the eggs were left?

6)You have a barrel of cokee and you need to measure out just one gallon. How do you do this if you only have a three-gallon container and a five-gallon container?

7) If you have 6 black socks, 4 blue socks, 8 brown socks, and 2 red socks in your sock drawer, what is the minimum number of socks that you need to pull out in the dark to be sure you had a matching pair?

Answers:

1) The key to this math riddle is realizing that the one place must be zero.
888 +88 +8 +8 +8 =1,000 

2) Both would weigh the same - come on, a pound remains a pound, irrespective of the object!

3) 3- You just took them yourself

4) Because then it wouldn't be a nose any more; it would become a foot! (12 inches and above - easy!)

5) Roosters dont lay eggs.

6)Fill the 3 gallon container with coke and pour it into the 5 gallon container. Then fill the 3-gallon container again and keep pouring it into the 5-gallon container till the latter is full to the brim. One gallon will be left in the 3-gallon container.

7)At least 5, so that at least one color has two socks
