If a place is affected by Tide at 6:00 AM Monday, normally at what time the same place will it be affected by Ebb?

It generally will take 12 hours and 26 minutes due to Moon's orbital orograde motion. Due to this motion, a particular point on the Earth on average needs 24 hours and 50 minutes to rotate under the moon. And this causes the time between high lunar tides to fluctuate between 12 to 13 hours more precisely 12 hours and 26 minutes. So going by that, if the tide hits a place at 6am on Monday, it will take 12 hours and 26 minutes which is 6.26pm Monday the same day.

The correct answer is 12:13 PM Monday.
A lunar day is a total time taken by the moon to make one orbit around the earth.
The moon is tidally locked to the earth. This means one side of the moon is always facing the earth.
The gravitational pull of the moon generates tidal force. The tidal force causes Earth and its water to bulge out on the side closest to the Moon and the side farthest from the Moon. These bulges of water are high tides.
The lunar day is roughly 24 hours and 50 minutes.
Because the Earth rotates through two tidal “bulges” every lunar day, coastal areas experience two high and two low tides every 24 hours and 50 minutes. High tides occur 12 hours and 25 minutes apart. It takes six hours and 12.5 minutes for the water at the shore to go from high to low, or from low to high.
Hence, the ebb would be affected at 12:13 pm Monday
