80% of 160 casual wear can be used swimwear. This is 160 x 0.8 = 128. This figure is the number of apparels that belong to Both the categories
No of casual wear + No of swimwear - Both + None = 300
160+200-128+None=300
None = 68.
Shouldn't the answer be 68?
No of casual wear + No of swimwear - Both + None = 300
160+200-128+None=300
None = 68.
Shouldn't the answer be 68?

Yes, I also got 68 using same formula. Yesterday I read the theory of the overlapping sets from the GRE MATH BOOK here, and it contained different scenarios and I couldn't grasp all and thus I am little bit skeptical of my answer although problem seems straight forward.
