Refer to figure, the absolute pressure of gas A in the bulb is

1. 771.2 mm Hg
2. 752.65 mm Hg
3. 767.35 mm Hg
4. 748.8 mm Hg

Correct Option: A

P_atm = 760 mm Hg

Let P_A be the absolute pressure at 'A'
Pressure at D = Pressure at E
or P_A + P_CD = P_atm + P_AF + P_FE

P_A +	170	= 760 +	50	+ 20
	13.6		13.6

P_A = 771.2 mm Hg
