The following picture shows a cage with 6 separate rooms made up of 13 sticks for 6 birds to stay.

Make a new cage with 6 separate rooms for the birds using 12 sticks.

Four friends Tom, Jim, Susan and Dora have 8 crayons in total which are two in each color – red, green, blue and yellow. While playing they have mixed up their crayons. All we know is each of the friends owned 2 crayons but none of them had crayons of same color.

One of the friends had a yellow and a blue crayon and another had a green and a blue crayon. Tom didn’t have a yellow crayon. Susan had a green crayon but not a red one. Jim had a yellow crayon. Dora had a blue but not a green one.

Which crayons belong to which friends?
