The Maid of the Mist carried exactly enough drinking water to last 100 people for the projected duration, and the Queen Elizabeth II carried exactly enough drinking water to last 1,000 people for the projected duration. Only one of the ships completed its journey with drinking water remaining. Which ship was this?

(2) Queen Elizabeth II carried 200 people, and the duration of its journey was 500% of that projected.

D

From 1 we know that there was extra water left and so it's the first ship that still had water left.

From 2, we know that no water was left on that ship, hence it was the other ship that came back with water.

option D

I initially answered A as i missed the term 'only one ship had water remaining'

st1. says that Mist carried 25 people and the duration was double the expected so half of its water is finished and still other half left.

st2. says that Queen carried 200 people and duration was 5 times the expected so all its water was over. which means the other ship is the one which had excess water.
