Containers A, B and C contains three different liquids with specific gravities of 1.2, 1.6 and 2.0 respectively. If the liquids in containers A and B are mixed, the resulting specific gravity is 1.36.When the liquids in containers B and C are mixed the resulting specific gravity is 1.8. Mixing liquids in containers A and C result to a specific gravity of 1.52. Determine the resulting specific gravity when the three liquids in the containers A, B and C are mixed together.
