i think the sum is wrong

you have to learn set theory to do this the answer by the ways is 400 people you dont use either if the brands.

and i am 1000% sure about my answer and the question is not wrong.

and the percentage will be 400/2500 * 100= 16 % is the right answer you could compare with answer.
