Hi!

Since the employee is 32 at the start of her employment, she needs to accumulate 70-32 = 38 "points" to retire.

Each year she works she gets 2 points - 1 for working and 1 for getting a year older. So, to determine how many years she needs to work, we simply divide 38 by 2 to get 19.

1986 + 19 years = 2005 as her year of retirement... choose C!

We will try to solve this question using inequalities here:

If Age is A, and the number of years of employment is Y, then following is the condition for retirement:
A + Y >= 70

If her 32nd birthday is in 1986, that means she was born in 1954, and if X is the current year
A = X - 1954,
and Y = X - 1986

(X - 1954) + (X - 1986) >= 70
X >= 1970 + 35
X >= 2005

So, she will be first eligible for retirement in 2005.

(C) is the answer
