Mr. Pawar,


Are you asking a question, or is it a test for others?
In any case the answer is as follows. (Answer - Total mangoes plucked = 9)

Let the total no. of mangoes be = x
The first boy gets, x/3 mangoes, leaving a balance of 2x/3 mangoes.
The second boy divides this into 3 & takes one extra: He gets, (1/3)*( 2x/3 ) +1= (2x/9)+ 1 = the first boys share ie x/3 Equate these and solve for x

x/3 = 2x/9 + 1 ==> 3x = 2x + 9. ===> x=9 ==> Each boy gets 3 mangoes.

Simple maths!

Subject:[Speak Out] How many MANGOES each one will get ?

Three boys make a plan to steal
mangoes from a garden. One climbs over the tree. Second one shows him the good mango inside of Leaves and branches. Third one keeps watch over watchman and collect the dropped MANGOES. Suddenly he sees a watchman, may see them. Soon he does 3 equal share of dropped MANGOES and goes away taking one part. Second boy also makes 3 equal share of remained amount and find one balance. He takes one share and balance one also and runs away. Last one also gets success to carry remained MANGOES and runs away. Later they meet a place and find that they all have equal share. Can you give the number how much each one gets from? What are the equations?

Dear Sir V Ramchandarn,

Your approach is correct but a little mistake is there.

Answer in other post is already given that is 2+2+2 = 6,
But Er. Abhio'expression in that post is hypothetic.
we can form such many equations , like wise of "x+1 = 2x" if 2x is each share.
for example :

x+2 = 2x, if x is share.

2x + 2 = 3x, if x is share.

现在可能是多个,但这些都不是日志ical, no base, not explanable with the problem conditions.

By a sense it is clear that answer should be multiple of 3, because it is being divided in 3 equal share.

Now try for 3,6,9,----and so on
by hit and trial,
Answer 6 is fit to the conditions, but answer 9 is incorrect.
(Readers himself may examine)
---------------------------------------------------------------------------

Another question framed of similar pattern (self made) ---



Three boys make a plan to steal mangoes from a garden.

One climbs over the tree.

Second one shows him the good mango inside of Leaves and branches.

Third one keeps watch over watchman and collect the dropped MANGOES.

Suddenly he sees that a watchman may see them. Soon he does 3 equal share of dropped MANGOES and escapes away taking one share.

Second boy also sees a little later, and he find that 3rd boy already escaped away hence he makes again 3 equal share of remained amount of mangoes and while doing equal 3 shares, he finds2 mangoesbalance.

He takes one share and balance2 mangoesalso and runs away.

Last one also gets success to carry remained MANGOES and runs away.

Later they meet at a place and find that they all have equal numbers of mangoes.

Can you give the number how much each one gets from?
What are the equations?

Hello Sir,

The total number of mangoes are-6
each one will take-2

Assume Total number of mangoes=y
first person took y/3 mangoes

second person take ((x/3)+1)mangoes where x=2y/3

equate 1 & 2 , becoz both should be equal

similarly with 2 & third equation

we get total mangoes=6

each one take 2 mangoes

Seems wrong just check.

Dear Er. Krishnaprasad,

Yes equation or expressions given by Mr. Sahay is wrong .
Because (2y/9) +1 = y/3 => will give ans Y =9, while ans is 6 hence wrong.

Answer 9 is also incorrect because After taking 1st share =3nos by 1st boy, when second will divide remaining =6nos, in 3 parts it will be equally dividable = 2x3 =6 and balance one will not be there.hence 9 ans is wrong.

Regards

[atul_123]

here i think i want to give ans as per my approach.


say total
MANGOES are 3x

first boy take 3x/3=x nos with him.


remaining
MANGOES are 2x



second boy divide it in 3, say he got y part each and find one extra MANGO and take so say that he take y + 1

and third boy take remaining 2y part

now as per starting total
MANGOES
是3倍

so total sum of three boys part is

x + (y+1) + (2y) = 3x .............................................. (1)




as per equation all have taken same nos so second boy take same as first boy so

y + 1 = x

so y = x - 1
so replace y by x - 1 in eq 1

x + ( (x - 1) + 1 ) + 2 ( x - 1 ) = 3x

x + x - 1 + 1 + 2x - 2 = 3x

4x - 2 = 3x

4x - 3x = 2

so x = 2


so total nos of
MANGOES are 3x = 3 * 2 = 6

i think it is right approach....

Dear Atul and all,

Yes you are correct. you proved mathematically.

But Logically you still away from the core bit of this problem.

Your solution is like that you have won title of the cricket match by Duckworth lewis method, but not clear cut.

You have given check the king of Chess, but not get him surrendered.

If it is any laughter show - you are getting 9 marks of course but not 10.

let we see

All 3 gets equal hence say = X each.
Hence total = 3X,

Now 1st gets = X ----- Eq 1


Now second receives 2X but while dividing it in 3 parts he gets 3 equal parts +1

Means = [(2X - 1) /3] + [(2X - 1) /3]+ [(2X - 1) /3]+1,
(here every body was committing mistake by doing = (2x/3) +1 -this is the wrong expression, and this is turning point of this question)

Thus Second will get as per condition given = [(2X - 1) /3] +1 ----- Eq 2

Third will get = 2(2X - 1) /3 ----- Eq 3

Equate all 3.
X = [(2X - 1) /3] +1 = 2(2X - 1) /3

Now solve any 2 eq will give X =2

Dear Friends,
I seem to have misunderstood the problem. I am giving the calculations in both the cases: I have also located the mistake.
Case 1 (9 mangoes) Case 2 (6 mangoes)
1. First boy sees (y ) 9 6
2. He takes 3 2
3. Balance (x) 6 4
4. Boy 2 takes (x/3)+1 2+1=3 (4/3) +1 = 2.1/3 not 2
5. Balance now for boy 3 3 1.2/3
The key word is: the second boy makes 3 equal shares of remaining mangoes and "finds onebalance”
In my calculations I have not accounted for the balance – which I have missed! The calculations are involving only integers, which means it has to be by trial & error method! Not “simple maths” as I remarked!
Thanks for the fun!
Best wishes,
V. Ramachandran.
