"Folk from Harvard, Princeton and MIT can't get it."

Can't be that hard - can it?

A baseball bat and ball cost $1.10. The bat costs $1 more than the ball. What is the price of each ?

When I was checking out a selection of schools for my kids, I asked the maths teacher "what is 2/3 of 3/4 ?". She could not do it in her head so that was the end of the interview.

Intrigued by the title of the thread - was this some survey where they couldn't answer the question?

Let's add some aviation content (and forget about the Princeton and MIT bunch):



Costs a tad more than $1.10 (or even 2/3 of 3/4 of that!).

Well, regardless of whatever the survey, quiz, or whatever was decided to show I'll bet most of the Harvard/ Princeton / MIT alumni can "get" an awful lot of stuff most of us can't.

I can't do it in my head either without waving my hands as if writing on a chalk board

Hint: It helps if you convert 3/4 to the equivalent in twelfths....

I found it easier to 'compute' (in my brain) what was 1/3 of 3/4 (easy) and then double it . . .

... and it helps even more when you realise that two thirds of three anythings is two of those anythings ...

Exactly that. No calculation is necessary.

There are three things, and you need two of them. Done.

3 guys walk into a store and each put 10 in to buy an item costing 30. After they walk out the manager says to the sales clerk you overcharged them, run out and give them back 5. On her way down the street to catch them she sticks 2 in her pocket and gives each of them back 1 leaving each of them now having paid 9, plus the 2 she stole totals 29! Where the foxtrot did the other pound go?

Old sheep farmer dies. He had a small flock & 3 sons. He decided to split to flock into 3 parts as inheritance for each son depending on their age. He divided the flock into 1/2 & 1/4 & 1/5. He had 19 sheep at this death and the sons were flummoxed. They had no idea and called the old neighbouring shepherd for help. "ney bother, I'll be right over."

He arrived with on of his own sheep and added it to the flock = 20 sheep. He then gave 10 sheep to the eldest son, 5 sheep to the next and 4 sheep to the next, and went home with how own sheep. Job done. QED.

I've always had a poor opinion of old sheep farmers.

Indeed. Says something about the peculiar way my mind works I guess.

Have you revised that now that they are smarter than the folks from Harvard, Princeton and MIT.
