Time : Total Grain moved in that period
12-1 800
1-2 800
2-3 800

So, till 3: 2400 pounds moved, (I is not possible)

III is not possible as by 4 it would have moved 3200 pounds.

So, answer is II only- 2400 pounds.

total weight moved in an hr ; 60/15 * 200 ; 800 lbs
so in 12-3 pm; 3* 800= 2400lbs
and 12-4 pm ; 4* 800 = 3200 lbs

question has askedelevator stops some time between 3:00 p.m. to 4:00 p. m so answer has to be in the range from 2400-3200 lbs ..

Archit3110 : If the weight is 2400, then the machine will be done at 3PM ,and it will stop after 3:00 PM. Even if it is 3:00: 01sec, then also it is b/w 3 and 4 PM. SO I think the options are correct.
