For an employee to qualify for early retirement at a certain company, the sum of the employee’s age and years of service must be at least 70, If Sue was K years old when she was hired by the company, what is the minimum age at which she could possibly qualify for early retirement.

A. K+35

B. 2K+35

C. (70+K)/2

D. (70-K)/2

E. 2(70-K)

Say Sue was hired when she was already 70 years old (k=70), then she could retire right away, at the age of 70. Now, plug k=70 in the answer choices and see which yields 70. Only C fits.

what a tough one..took me some time to solve. suppose k=20 after 10 years of experience: 30 years, 10 experience = 40 - not enoguh 10 more years 40 years, 20 years experience = 60 total - not enough 5 more years 45 years, 25 experience = 70 total. so at 45 she can retire.

plug in values A: K+35 = 55. out B: 2K+35 = 75 - out C: (70+20)/2 = 45 - hold D: (70-20)/2 = 25 - out E: 2(70-20)=100 - OUT.

HI, If we get hang of what is asked, we can easily do the Q..

INFO FROM Q

1) the sum of age and service should be atleast 70 2) Sue was K yrs old when hired..

WHAT has to be found

minimum age when Sue can retire? what does this mean- it means she retires at exactly when total is 70.....

SOLUTION

1. Sue's age= k.. so she has to cover remaining period 70-k..

2. in how much time can she cover this= (70-k)/2 WHY?.. because EACH year accounts for TWO years increase, one in AGE and one in SERVICE...

3. so Sue after joining at age of K years can take earliest retirement after (70-k)/2 years..

4. what will be her age then-- k+ (70-k)/2 = (2k+70-k)/2= (70+k)/2..
