If I had one more sister I would have twice as many sisters as brothers. If I had one more brother I would have the same number of each. How many brothers and sisters do I have?

At the scene of a heinous crime, five suspects, one of whom is the guilty party, are being interrogated by a detective. Each of the suspects gives one statement and it later transpires that just three of these statements are correct.

These are the statements:
Uncle Jack: Uncle Jim committed the murder
Aunt Mary: I did not do it
Cousin Stewart: It was not Cousin Margaret
Uncle Jim: Uncle Jack is lying when he says I did it
Cousin Margaret: Aunt Mary is telling the truth

Who committed the murder?

A genie transformed Abou, the merchat and his three brothers into animals. He turned one into a pig, one into a donkey, one into a camel, and one into a goat.

1. Ahmed didn’t become a pig, and he wasn’t a goat
2. Sharif wasn’t a camel, and he wasn’t a pig
3. If Ahmed was not a camel, Omar was not a pig
4. Abou didn’t become a goat, and he was not a pig
5. Omar was not a goat nor was he a camel

What did each of the brothers become?
