130 iQ question [part 2]

[Spartacus1-]

A miner has to travel as lightweight as possible in order to reach remote villages where he plans to buy some gems. In his shop he has a portable balance scale and weights counting from one to a hundred grams. He needs to be able to weight pieces up to a hundred grams.

What is the minimum number of weights he can take with him and which ones considering in some cases he might have only one gem to weight?

 

[needsolution]

Im too high IQ to anwser this. I will do it with 200iq question, till then cya.

 

[TUSSELEIF]

1 probably. Idk I'm too low IQ

 

[Finalchad]

Take a gun, kill everybody, take all gems. Rape the foids. Its remote afterall.

 

[Spartacus1-]

@TsarTsar444 here's your part2

 

[Deleted member 6902]

100

 

[Spartacus1-]

I guess this is a bit too hard. Fair enough ill provide an answer later on if nobody will do as such.

How does a balance scale even work?

 

[Deleted member 6475]

I am retarded i just dont have the attention span to think this through to i could quite honestly

Explain your results

 

[Finalchad]

Its not too hard, im just too lazy to calculate. Too low iq to do it in my mind thouhgh

 

[AbandonShip]

How can i even answer this? The gems have no fixed weight. Or maybe i dont understand the problem

 

[Deleted member 3323]

I feel like this question is worded badly. Is English your first language? Weigh is to determine the weight of an object while weight is to add weight to something, in order to make it heavier.

 

[OldRooster]

Explain your results

seems self explanatory. I have encountered similar circumstances going to auctions, selecting what check amounts to bring. In those cases I worked backwards. But here you had to start with 1 as it was implied that there were no fractions. I suppose you could have started at 0.01 and gone up from there.

Or I suppose the last weight could have been 100-32-16-8-4-2-1=37 just to make it fractionally lighter.

gram

gram

So one gem weighs one gram?

It's not worded badly. You just didn't comprehend it

 

[AbandonShip]

My iq is so low that i dont even understand the problem

 

[Deleted member 3323]

You cant say "To weight" "I want to weight this"

It doesn't make sense.

The correct word is "Weigh" "I want to weigh this."

I grew up as a native English speaker and I never heard some say "I want you to weight this."

I don't even understand how a balance scale workd dfack

There are two questions being asked: minimum weight and minimum number of weights.

 

[AbandonShip]

I don't even understand how a balance scale workd dfack

It works by balancing of torques. If you put two equal weights on each side then it will balance out perfectly, otherwise it'll tilt to the heavier side

 

[Spartacus1-]

The official answer
1+3+9+27+60=100

100 weights of 1 gram each.

I don't get this question tbh, suppose there is a 5gr gem, you need a 5gr weight to measure it, then what?

Just carry 100 1 gram weights

 

[TsarTsar444]

Just carry 100 1 gram weights

This sounds like the correct answer

 

[Deleted member 2352]

Jfl my IQ is 106
Makes sense Since i didnt even understand the question

 

[AbandonShip]

This sounds like the correct answer

You can measure the most accurately using this. The overall weight would be 100 gram so no extra weight problem. Even a retard could figure this out

The official answer
1+3+9+27+60=100

Why not carry 1gmX 100= 100 weights?

 

[TsarTsar444]

You can measure the most accurately using this. The overall weight would be 100 gram so no extra weight problem. Even a retard could figure this out

The problem with the question tho is that he only has weights fro 1 to 100 grams

 

[AbandonShip]

Fuck you op idc shit thread ooga booga

The problem asked for the minimum weigh

 

[AbandonShip]

The problem asked for the minimum weigh

Idk and idc

 

[Slayer]

OP I CAN TELL BY THE WAY YOU TYPE THAT YOU'RE EASTERN EUROPEAN AND THUS I CANNOT UNDERSTAND THIS QUESTION

 

[Viro]

REE I THOUGHT OF THE POWERS OF 2 NOT 3. YOU CAN SOLVE THIS BY CONVERTING ARITHMETIC SYSTEMS. IN THIS CASE YOU CONVERT BASE 10 TO BASE 3 BECAUSE YOU NEED LESS WEIGHTS TO REPRESENT THE RANGE [1,100] IN BASE 3 THAN BASE 10. fuck i so sure it was base 2 now im sad because turns out im a brainlet. over

If we had the weights and scale in front of us it would have been a lot easier to solve.

thanks for soothing my pain

1 2 3 4 5 6 7 8 9 10 45
Nvm.I re-read and it asks for the minimum nr of weights so a better solution would be 1 2 3 7 12 25 50

 

[Deleted member 275]

The official answer
1+3+9+27+60=100

makes sense.

No u dont need the 2 grams weight, if a gem weigh 2 grams then u can just put the 3 gram weigh on one side of the scale and on the other side where the gem is u have the gem plus the 1 gram weigh, thus weighting the gem without using a 2 gram weigh.

This applies also for the 7 grams weigh u mentionned if u use a 9 grams plus the 1 gram weigh, and on the other side the 3 gram weigh plus the gem. If u add a 12 grams weights, that then allows u to weigh up to 27 grams gem.
U continue the reasoning like this and u get the answer op posted.

Jfl at my brain . I didnt think you could use the weights on the other side of the scale.
