What is the absolute pressure in a piping system when the vacuum gage reads 20" and the barometer reads 30.71" of mercury?
Presumably abstract.
In answer to the original question, when they ask these sort of questions on university challenge the answer is usually 1, minus 1 or zero so I will say the answer is 1!

if they are inches mercury then the answer is
P_abs = 30.71" Hg - 20" Hg = 10.71" Hg

It's not a trick question, just worded with imprecise language.
