Where did this 101.3 over 76 coming from?

Its not on the given.

Here is the picture.

 

3. Point A in the suction pipe is 1 m below the pump. It is mounted with an open manometer which reads
a vacuum of 20 cm of mercury. The pipe is 10 cm in diameter and the flow is 35 liters/s of water. Compute
the total energy at point A with respect to a datum through the pump.
Solution:
Given:
P = 20 cm H
101.325 kPa
