问题 I bought four things this morning. The dictionary was 5 times the cost of the book, the tie was 30 times the cost of the book, the Watch was 4 times the cost of the tie, and I spent 312 dollars in total. What was the price of the dictionary?

选项

答案 10

解析假设字典的价格为x，那么书的价格为1／5x，领带的价格为30×1／5x，手表为4× 30×1／5x，这些东西的总价值为312，因此可得方程式X+1／5x+30×1／5x+4×30×1／5x=312，故x=10。
