Total no of marbles in bag A & B is 352 more than 1/5 of marble in bag A. Find marbles in Bag B.

 

Is there something wrong with this question or simply i'm not good enough? keke

 

Thanks in Advance.

Don't try using algebra. Use the primary school model method.

I thought I'll give it a shot but it drove me crazy! Primary school method? Care to share? I was really perplexed. My quadratic equation suddenly became ridiculously huge and unthinkable hahahahaha

There is no fixed answer to this question. It is more of a 'creative thinking' rather than the fixed route maths we used to learn in the past.

 

Qn: A+B = 352 + (1/5)A

 

Ans1: A=5, B=348

Ans2: A=10, B=344

Ans3: A=20, B=336

Ans4: A=100, B=272

 

The trick is A must be a multiple of 5. Just assume any number for A. To get B, follow equation i.e add 352 + (1/5)A - A.

i tried A+B = 352 + (1/5)A too

 

but answer not logical if u notice

 

will end up both answers are "=" in the substitute equation

 

more like a f(x) question or trial n error question to me

This is how maths questions are phrased. more than does not equate directly to >

 

What qn means is A+B = 352 + (1/5)A

 

if you mean A+B > 352 + (1/5)A, then same method works. A must be a fixed multiple of 5. Assume any number for A. To get number B, assume any number bigger than the sum of 352+(1/5)A .

 

Qn: A+B>352+(1/5)A

Ans1:A=5, B=1000

Ans2:A=5,B=500

Ans3: A=100, B=1000

bag B can be any number that satisfies the 2 requirements.

 

1) multiple of 4, including 0

 

2) ranging from 0 - 348

 

why multiple of 4?

 

Let A be 5X, and B be B

since 5X + B = 352 + X

4X + B = 352

4X = 352 - B

 

In order for this equation to be without any decimal places for X, B must be a multiple of 4.

And B can be 0, as 352 is a multiple of 4.

 

why ranging from 0 - 348 only?

 

if not it will not satisfy the equation 4X = 352 - B

If B were to be between 349 - 352, X would be in decimals

IF B were to be bigger than 352, X would be negative.

 

I hope this answers your question.

Yup, this was what happened to me while just trying this question. I went from A+B=352 + A/5, then became quadratic equation, to thinking it had to be a multiple of 5, to duno what already lolz. But since this is a question, shouldn't there be a definite answer? Rather than attempting to deduce from creative solutions which puts A as a multiple of 5?

 

TS, where did you get this question from and is there a formal solution provided? I'm extremely curious.

with this line. cannot be solve.

honestly,

 

I would just count the number of marbles .

 

If this kind of math trains the mind for exam papers, than exam papers are too far from problems in reality.

Dont bash for the sack of bashing.

 

This kind of math is the reason why we have one of the best math system in the world. Even other country want to learn from us.

 

The only problem is with the english of this paper.

If this is a primary school question, some information has been left out. Thus cannot be solved.

 

If this is a secondary school question, then there are multiple answers.

 

Since question stated 1/5 of A, A must fulfil 2 criteria:

1) A more than or equals to 5

2) A is in multiples of 5

 

A + B = 352 + A/5

 

B = 352 - 4A/5

 

5B = 1760 - 4A

 

If A = 5, B = 348

If A = 10, B = 344

 

So on and so forth.

Perhaps if we try to read it in the mother tongue of the person who set the question, we might understand better? [:p]

I think also difficult. cause more than 1/5 could als mean its 4/5 you know... [laugh]
