The answer is not in the option
h= difference in levels in the two arms of the manometer
(10-7)=3m
Since the answer in in millimeter and our h is in meter
Recall 1mm-0.001m
Therefore 3m will be 3000mm
Gas pressure=atmospheric pressure+h
=760+3000
=3760

If the pressure at G is same as the atmospheric pressure, then the barometric fluid would have been at the same level on both sides. But because the pressure at chamber G is higher than the atmospheric pressure, the fluid tends to push the atmosphere upward by, 10 – 3 = 7= 70mm.
This means that the actual pressure at chamber G,= 760mm + 70mm = 830mm
