stock number of shares
v 68
w 112
x 56
y 94
z 45
The table shows the number of shares of each of the 5 stocks owned by Mr. Sami. If Mr Sami was to sell 20 shares of Stock X and buy 24 shares of stock y, what would be the increase in range of the number of shares of the 5 stocks owned by Mr Sami?
A 4 B
Answer: D
我认为是A, 24-20=4
range before transaction
112-45=67
rang after transaction
(94+24)-(56-20)=118-36=82
the difference is
82-67=15
hope it helps~~
谢谢,但是为什么要这样做,我还是不太明白.
为什么rang before transaction 是那样计算的?
我在做gmatprep的时候也有个数学题比较ft
*X=3X,当x是odd的时候, *X=X/2, 当x是even, 然后问*9X*6=?
我选81, 答案是27, 哪位帮忙看看怎么回事

LZ是不是range的概念没想清楚,就是集合当中最大的元素与最小的元素之差呀,当然是112-45呀。

GG是对的,估计是bug
我明白了,谢谢大家了.
