10% of salty sea water contained in a flask was poured out into a beaker. After this, a part of the water contained in the beaker was vapourised by heating and due to this, the percentage of salt in the beaker increased M times. If it is know that after the content of the beaker was poured into the flask, the percentage of salt in the flask increased by x%, find the original quantity of sea water in the flask.
