Find how many skirts she bought.. for this we should know price of each skirt and total amount spent.

option 1: just give value of each skirt . Not sufficient.
option 2: just given total amount spent. We don't know cost of each skirt so we cannot find number of skirts bought. Not sufficient.

option 1+2
now we know both ... price of each skirt and total amount spent. So we can calculate no. of skirts bought.
