今天是考试的第四天。。。考数学。。。
有一个问题弄到我很乱，那个问题差不多是这样：
Encik xxx have 360 rambutans. He sold 7/12 of the rambutans. He found 1/4 rambutans are rotten and throw it. How many rambutans were not sold out?
看起来很简单？？？
问题在。。。他问还有几个红毛丹还没卖出，可是我不知道坏掉的要不要算进去。。。
我是这样做的：
Rambutans were sold : 360 x 7/12 = 210
Rambutans were rotten : 360 x 1/4 = 90
Rambutans were not sold out : 360 - 210 - 90 = 60
对还是错？
