Correct answer
C
All departments other than electronics means clothing, books, and home goods: 300 + 100 + 200 = 600. Clothing is 300, so 300 ÷ 600 = 50%. So the answer is C.
Dividing by the full $1000 total with electronics included gives 30% (choice B), but the stem explicitly excludes electronics, so the base must be 600.
Choice D, 60, drops books and divides clothing by the clothing-plus-home-goods base of 500: 300 ÷ 500. Choice E, 75, uses a clothing-plus-books base of 400: 300 ÷ 400. Choice A, 25, comes from treating the four departments as equal shares and counting clothing as 1 of 4 departments: 1 ÷ 4 = 25%, which ignores the actual dollar amounts.
