[計量] 一題曼哈頓的PS
In a certain game, a large bag is filled with blue, green,purple and red
chips worth 1, 5, x and 11 points each, respectively. The purple chips
are worth more than the green chips, but less than the red chips. A certain
number of chips are then selected from the bag. If the product of the point
values of the selected chips is 88,000, how many purple chips were selected?
a 1
b 2
c 3
d 4
e 5
ans: B
麻煩指點一下
我看解答不太懂 特別是他提到11一定是紅色chip, 我覺得難道red chip不能是5嗎?
謝謝分享
