After a half hour a third will go..
216x1/3=72 (go)
216-72=144 remaining after half hour
From the remaining 144, another third will go
144x1/3=48 (go in the second half hour=after an hour)
144-48=96 (left after an hour)
Therefore answer is d -96
216x1/3=72 (go)
216-72=144 remaining after half hour
From the remaining 144, another third will go
144x1/3=48 (go in the second half hour=after an hour)
144-48=96 (left after an hour)
Therefore answer is d -96

The question asks how many remain after the first hour.
216/3 = 72
72/3 = 24
216/3 = 72
72/3 = 24
