PP-T1-DS-141

[sunnyblue13s]

141. To fill an order on schedule, a manufacturer had to produce 1,000 tools per day for n days. What is the value of n ?

(1) Because of production problems, the manufacturer produced only 600 tools per day during the first 5 days.

(2) Because of production problems, the manufacturer had to produce 1,500 tools per day on each of the last 4 days in order to meet the schedule.

爲什麼不能選擇"C"??

(1)+(2) = (600*5 + 1500*4)/9 =1000
這樣 n 不就等於9了嗎???

爲什麼這樣不行ㄚ??
