### HideShow timer Statistics

A certain company retirement plan has a "rule of 70" provision that allows an employee to retire when the employee's age plus years of employment with the company total at least 70. In what year could a female employee hired in 1986 on her 32nd birthday first be eligible to retire under this provision?

A. 2003
B. 2004
C. 2005
D. 2006
E. 2007

[Reveal] Spoiler:
According to my sol

32+x=70
x=38

as age is also increasing with the increasing number of years we can't count the years twice 38/2=19

year of retirement will be 1986+19=2005

Any other explanation!

Your solution is perfect. One can also do:

She must gain at least 70 points, now she has 32 and every year gives her two more points: one for age and one for additional year of employment, so 32 + 2*(# of years) = 70 --> (# of years) = 19 --> 1986+19=2005.

X is the years worked

32+x+x>=70

2x>=38, so x>=19

1986+19=2005

C

or other way around is 70-32=38

so 2 score each year....>>>>>38/2=19 1986+19=2005

Great question!!!

There is a pattern to observe if you draw a table -

Check every year there is an increase in 2 years

We need to go from 32 to 70 ; so we need need to have 38 points....

Now since each year make 2 points increase 38 will take 38/2 =19 years from 1986 => 2005

Hence answer will be (C) 2005

In 1986, her number is 0 + 32 = 32.
Each year after, she has 2 added to her number. So the number of years it will take for the number to reach 70 is (70-32)/2 = 19
The year in which this happens, of course, is 1986 + 19 = 2005.
