Paheli went to the market to buy sarees for her mother. She took out a thread from the edge of the two sarees shown by the shopkeeper and burnt them. One thread burnt with a smell of burning hair and the other burnt with the smell of burning paper. Which thread is from a pure cotton saree and which one from a pure silk saree? Give a reason for your answer.
The thread that burns with the smell of burning hair is from pure silk saree and the thread that burns with the smell of burning paper is from pure cotton saree.
