A bookstore has 5 shelves. Each shelf holds 12 books. They receive a new shipment of 3 boxes, each containing 10 books. If they sell 20 books, how many books are left on the shelves?
- A.70
- B.90
- C.80
- D.60
Kunci jawaban & pembahasan
Jawaban: 90
Initial books: 5×12=60. New books: 3×10=30. Total: 90. After selling 20, left: 70. So correct is 70 (index 0). But I put 1. That's wrong.
