Answer
In the given condition, $p_{atm}$ = 1 bar = 100 kPa,
Since the pressure in the tank is 200 kPa, it is greater than the atmospheric pressure by 100 kPa. We know that Bourdon reading is the gauge pressure , also,
$P_{gauge}$ = $P_{abs}$ - $P_{atm}$ =( 200 - 100 ) kPa.
therefore the bourdon reading is 100 kPa
