Henry will lift 200 N load 20 m up a ladder in 40 s.  While the Ricardo will take 400 N load in 80 seconds. So, For Henry to take 400 N load it will take him 80 seconds in two attempts. And,also, he will have to cover 40 m of distance. 

Answer;

-Ricardo exerted a greater force, did the same amount of work, and had the same power output as Henry.

Explanation;

For Ricardo to lift twice the load lifted by Henry for the one-half the distance in the same amount of time, he will need more force as the load is heavier.
