我的解读如下
在欧美茄公司 若想获得退休补助金
则此退休员工的年龄加上其在公司服务的年资 需大於70
假设今天A员工於x岁进入公司(x小於70)
y是他想获得退休补助金 需在公司服务的最低年资
下列哪不等式选项最能表现出X Y之间的关系?
假设他服务了Y年 进来时已经是X岁
故达最低可领退休辅助金的门槛时 他应该是(x+y)岁了
根据题目问 想领退休辅助金最少需服务几年?
故方程式可列为
(x+y)+y=70------> (D)2x+y=70
※ 引述《sandisk (.)》之铭言:
: To be eligible for retirement benefits at the Omega Corporation, the sum of
: an employee's age, in years, and the number of years of employment must be at
: least 70. If x, where x < 70, is a certain employee's age when hired and y
: is the minimum number of years of employment required for the employee to be
: eligible for retirement benefits, which of the following equations represents
: the relationship between x and y ?
: A. xy = 70
: B. x + y = 70
: C. 2x + y = 70
: D. x + 2y = 70
: E. 2x + 2y = 70
: Answer: D
: 就看题目的意思很像是B
: 不懂为什麽答案是D
: 谢谢解答
