write pressure equation for both tubes.

Explanation:

write pressure equation for the two tubes :
as we know , pressure at same height is same .
P_a - rho*g*(13.2-3.5)/100 = P_g
P_a - pressure due to atmosphere
P_g - pressure due to the gas
rho - density of liquid in the tube
putting the values in the above equation , you can obtain the pressure exerted by the gas in the column BC .
