Mike started working at 18 and retires at 60. He spent the first 1/5 of his working life in a school, 1/3 of his working life in a corporate office, and 1/4 of his working life as a consultant. For the last 16 years, Mike has been managing his own business. How old is Mike? Round to the nearest integer.

B) 62
C) 68
D) 72
E) 78


In my opinion, the problem's source provides wrong answer. Could you confirm that my answer is indeed correct ? Thx in advance.

Hi,
as you have said that answer cannot be A..
The WORDINGS of the Q are not very clear..
1) Even if I take that whatever he did in his working life is OK and he retired at 60..
2) the only other thing given is taht he is managing his business from last 16 years..
so if he started doing this after retiring, he should be 60+16=76 at the max..
3) retires at 60 shows he has not retired as of now..

From where this MAGIC number of 92 has come is not understood..

Question language is tedious as question taker will construe all given part of working life within his tenure. Therefore, he'll answer 60+16=76.

The working life is split as below:

x = (1/3 + 1/4 + /15 )x+ 16 yrs

from this it can be calculated that the total working life is 74 years approx

Since the working life started at 18, the answer is 18+74 = 92 yrs

Answer: A
