※ 引述《chenemily (天天保持好心情)》之銘言:
: A department manager distributed a number of pens, pencils, and pads among
: the staff in the department, with each staff member receiving x pens, y
: pencils, and z pads. How many staff members were in the department ?
: (1)The numbers of pens, pencils, and pads that each staff member received
: were in the ratio 2 : 3 : 4, respectively.
: (2)The manager distributed a total of 18 pens, 27 pencils, and 36 pads.
: 請問一下 C為什麼不可以
: 有(1)的比例+(2)的數字 不可以嗎
: 還是哪邊錯了 = =a?
其實第一個條件被第二個條件 cover 住了
大家都有一樣筆數 所以 18:27:36 就是
平均一人的 pens pencils and pads 的比例
所以有可能是 9人 也有可能是 3人
