My answer is..










All students who were trying to attend the prestigious Massachusetts Institute of Technology Entrance exam were asked this over 100 year old Math question that stumped a lot of students.and it sounds relatively easy but the question isn't as simple as it sounds as only the brightest math wizzes know the equations to do it....can you solve it?..

Two years ago the son was 16 and the dad was 48 (16x3). They are now 18 and 50. Fourteen years hence the son will be 32 (18+14) and the father will be 64 (50+14). What were their ages? 16 and 48.

18 and 50

Present day = 18 year old and 50 year old
Two years in the past = 16 year old and 48 year old (16*3=48)
14 years in the future from present day = 32 year old and 64 year old (64/32=2)

You can eliminate 3 of the answers directly off the bat. Then you can eliminate the 4 others by literally just going a single step further.

If MIT people can't solve that then there is a massive problem.

I noticed this too, but if we're playing semantics the switch from first to third person means the question could be about other people entirely, so it could just be poorly written. Which wouldn't really be surprising given the source

The "were" could mean what were their ages when the statement was said, as we don't know when this conversation happened

It has to be the smaller pair of numbers you're talking about. The "two years ago" implies that the present day is the +2 version. You don't use "were" unless you're talking about past tense or sometimes hypotheticals.
