What is the capacity of a fire reservoir, in thousands of cubic meters of water, which is currently filled up to three quarters of its capacity?
1. If 3∗10³ thousand cubic meters of water were pumped into the reservoir, it would be filled to 7/8 of its capacity.
2. If 6∗10³ thousand cubic meters of water were removed from the reservoir, if would be filled to 1/2 of its capacity.
