Havard students get near-perfect SAT scores. These are smart, smart kids. So they shouldn't have trouble with a simple logic question, right?

Try the following puzzle:

A bat and ball cost \$1.10.

The bat costs one dollar more than the ball.

How much does the ball cost?

I’m inclined to say “A nickel,” meaning that the ball costs 5 cents and the bat costs a dollar and five cents, making the bat cost a dollar more than the ball.

I’d be inclined to say, “we don’t know” because we don’t know if there is a market for balls when not paired with bats.....

Must be in a right-to-work state. In a union-thug state, they would cost \$47.50.

That's racist. Probably homophobic too.

I'm not sure why they call it a logic problem- it's clearly a math problem that can be solved with the simplest algebra: 2X + 1.00 = 1.10

2X + (1.00- 1.00) = 1.10 - 1.00
2X = .10
X = .10/2
X = .05

Do they not teach math at Harvard?

Homoerotic, actually ... or a rape imagery.

"Bat"??? "Ball"???

Come on ... we all KNOW what they're really talking about!

Thus endeth my attempt at replicating the 'Feminist/Queer Studies" answer to the question.

Is that \$1.10 before or after sales tax?

The bat cannot possibly be a dollar more than the ball, because the value of both together after taxes is about \$.40. The question is flawed.

Two equations two unknowns:

X + Y = 1.1

Y = X + 1

Therefore 2X + 1 = 1.1

2x = .1

X = .05

My first instinct was to say 10 cents then it struck me that would mean the bat cost 90 cents more.

Of course it is a nickle.

The ball is 0.05
The Bat is 1.05 which is 1.00 more than 0.05
The total is 0.05 + 1.05 = 1.10

It’s not right that some should have bats and balls when others cannot afford them nor should bats only be viewed as being paired with balls. It’s perfectly acceptable that you can have 2 balls without bats and it is also acceptable that you can have two bats without balls. This question is just a product of linear male thinking.

Formally,

Let X be the price of the bat and
Let Y be the price of the ball.

X+Y=1.10 -— Eq 1
X-Y=1.00 -— Eq 2

Solve the equation simultaenously:

2X=2.10 (Step 2)
X= 1.05 (step 3)

From Eq 2:

1.05-Y= 1.00 (Step 4) (substitute 1.05 for X )

Y= 1.05-1.00 = .05 (Step 5)

Therefore:

X (Price of bat) = 1.05
Y (Price of ball) = .05

(Of course, in an actual TIMED test, you have to act fast and don’t have the luxury of doing the above ).

I was engaged to a little cutie who lived in Texas. We had met and spent the Summer at a mountain retreat.

Just before classes began, I drove to Texas from Florida to visit her parents. Her Father was a genius who held a large number of patents, He was a chemist for Dow Chemical.

The first morning after I awoke but she was still asleep, Her Mother made me breakfast. Her Father was fiddling with a magazine which had a bunch of brain teasers in it. He asked if I liked doing them and I said truthfully that I did.

We worked several of them and I realized the whole thing was a test to see how smart his future Son-in-Law was.

Anyway one of the questions was this: You have 5 pieces of chain. Each piece has 3 links. You decide to make them into a single long chain.

You take them to a blacksmith and he says he will charge a penny to cut a link and 2 cents to weld a link back together. What is the cheapest you can have the job done.

The answer is 9 cents. I guess I passed as he said I was the only person who had ever given the correct answer.

I used two variables and two equations:

x+y=1.10
x-y=1.00
-----------
2x = 2.10
x=1.05
y=.05

I haven't used that algebra in 50 years, but it gives the right answer, so I guess it's correct.

If weeping, wailing boner had balls would both of them be worth a dime?

If obama had balls, Reggie Love would still be his manlove and would be massaging his \$ 1.05 bat.

This isn't a logic problem, it's a 5th grade basic arithmetic problem and one of the easier ones to do.

Here’s another logic test Harvard grads fail:

You are spending 40% more than your income. Should you

a. Increase Spending
b. Decrease Spending.
c. make your own dollar bills.

I just started at the ball = 0.0 and added the values of the bat at 1.00 more.

So I just quickly walked the values up like so
0.00 + 1.00 = 1.00
0.01 + 1.01 = 1.02
0.02 + 1.02 = 1.04
0.03 + 1.03 = 1.06
0.04 + 1.04 = 1.08
0.05 + 1.05 = 1.10 - bingo!

This is the fastest way to do it in your head, doing the algebra takes more time and the test may have a time limit.

Like with IQ test questions the answer than immediately comes to mind (0.10) is pretty much always false.

Say, whatever really happened to Reggie Love? I miss him, and so does Barry! Is there a new man in the playroom? I tried to call Valerie, but she won't pick up.

Enquiring minds need to know. Should I ask Michelle?

A smart politician should never be caught with a dead girl or a live boy, so I guess Barry be smart.

Don’t need algebra. Need a brain. The answer is the remainder of the difference between the 2 (.10)divided equally (.05).

No, we attended different colleges and after a few months she told me she thought she was in love with someone else. I was really devastated.

Anyway I ended up married to an even more beautiful girl. Oddly I kept in touch with a mutual friend who told me the Texas girl later broke up with the boyfriend. In the meantime I got married. After she found out that I was married, she went back to the boyfriend, they got married and from what I have heard, had a happy marriage. They also have 5 children.

Urkel would say “The ball represents centuries of oppression and is probably made by the criminal 1%. It should cost nothing and I am introducing a bill that everyone below the poverty line receives a new ball every week.”

0bama/Harvard math:

a=b
a² = ab
a² - b² = ab - b²
(a – b) (a + b) = b (a – b)
(a – b) (a + b) = b (a – b)
(a + b) = b
But a = b, therefore
a + a = a
2a = a

hence
2 = 1

So we can double the taxes on the rich and they come out OK. Got it?

We can acquire the raw materials for 5 cents, but with the right synergy between public and private sectors, we can probably charge taxpayers \$2,300.
