Q35. A clothing store acquired an item at a cost of x dollars and sold the item for y dollars. The store's gross profit from the item was what percent of its cost for the item?
(1)y-x=20
(2)y/x=5/4

題目看不太懂
麻煩大家了
謝謝

The gross profit from the item 應該是Y-X
cost for the item就是X
題目問Y-X是X多少% -> (Y-X)/X *100%=?
(1)解出分子而已 not sufficient
(2) (Y-X)/X=Y/X-1=5/4-1=1/4
可知道是佔25%
所以應該是B
