What then is the gauge pressure at the bottom of the water?

** I got 4000 Pa

By how much must the water level in the container be reduced, by drawing some water out through a valve at the bottom of the container, to return the gauge pressure at the bottom of the water to its original value of 2500 Pa? The pressure of the air above the water is maintained at 1500 Pa above atmospheric pressure.

** Here I was thinking of 1500 Pa / 1000 = 1.5 --> 1.5/9.8 ???
