1 gram of CaC03 was dissolved in dil. HCI and the solution diluted to1

1.	1 gram of CaC03 was dissolved in dil. HCI and the solution diluted to1 litre. 50 mL of this solution required 30 mL of EDTA solution while 50 mL of hard water sample required 15 mL of EDTA solution. On the other hand, 50 mL of the boiled sample of hard water when titrated against EDTA consumed 10 mL of the solution. Find out each type of hardness and express it in ppm of CaC03 equivalents.
