first of all this is not question of modern physics it is from work , energy and power
ratio is 1:3:5 , as  work = force * displacement
and force is same in all three that is (mg)
and ratio of displacement in consecutive time interval is 1:3:5
so it is the answer

look its quite simple
a ball is released at some ht during its motion it will experience force of gravity
and in the question we have to find out ratio of work done by gravity in consecutive time interval    ,, ,thats it
and u must be aware of this ratios that ratio of displacement in consecutive time interval is 1:3:5
