The salt from a bin is to be packed into bags. If I put 10g
of salt into each bag, there will be 7g short. If I put 9g of salt into each
bag, there will be 4g extra. Find the mass of the salt in the bin.
The weight of the salt in the bin is 67g. Because if you divide 10 from 67,there will be a remainder of 7.If you divide 9 from 67,there will be a remainder of 4.
