At 12:00 noon, a machine, operating at a fixed rate, starts processing a large set of identical items. At 1:45 p.m., the twenty-first item has just been processed, and 15 have not yet been processed. At what time will all 36 items be processed?
A. 2:25 pm
B. 3:00 pm
C. 3:27 pm
D. 4:13 pm
E. 5:15 pm
The OA is B.
It takes 1h and 45 minutes to complete 21 items.
1h45m=7/4h.
Rate=21/(7/4)=12items/hour. 36 items are ready in 3 hours from noon. Option B.
Has anyone another strategic approach to solve this PS question? Regards!
