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。
