calm down.. didn't you say you wanna be saved from your drowning deep into yourself ?

rule #1 do not retaliate deflect and absorb and purge.

 

Yeah, I can't believe that being super irritating myself, I can be irritated by someone else more irritating

tried to read the question and I almost fall asleep lol.

 

anyway since I had nothing better to do I decided to attempt this question, tbh I did complete it within 5 mins but spent a min or so sending smses and I admit I used it with calculator.

 

9876 / 3 = 3292

hall 3 initial chairs = 3292 / 2 = 1646

1646 (1/3) chairs were transferred from hall 2 to hall 3.

1646 x 3 = 4938 (number of chairs in hall 2 after hall 1 transferred chairs to hall 2)

number of chairs transferred from hall 1 to hall 2 = 3292 / 4 = 823

so number of chairs in hall 2 initially = 4938 - 823 = 4115

 

I hope I am right here, too long didn't attempt any maths question. but I guess for a primary 6 student shouldn't be that hard right? since from what I know, children nowadays are studying things that are harder than the past.

 

 

Is it just me?? But i think that not enough info provided to solve this question..

3 halls = 9876 , but does not state that it was divided equally.

I think you need to read the question more carefully. All info required to solve the problem can be found in the question.

Reverse calculate and it's simple.

In the end it was equal.

Maybe it is the Ministry's intention to have the young citizens prepared to face the world after having completed primary 6.

This father is going to be mocked at. This question is easy!

 

#of chairs in second hall = 9876/3 + (9876/3/2) - (9876/3/4) = 4115

 

You are a genius!

 

Anyway here's my solution:

 

Each hall = 9876/ 3 = 3292

Hall 3 has at first = 3292/2 = 1646

 

Hall 1 has at first = 5 units

Hall 1 left = 5 - 1 units

= 4 units = 3292

 

1 unit = 3292 /4 = 823

 

Hence, Hall 2 has at first = (1646 X 3) - 823 = 4115 (ans)

your though process is better than mine i must say.

 

i broke it down into more steps

hahaha.....i rem when i was young, i had a teacher who used to punish those who blatantly read the question wrongly by smacking them with ruler. Tough love, but it works

for a 12yr old i think this is NOT easy

 

even an adult need to write it down to get ans

 

anyway my 'model' ans:

 

let x=3rd hall, y=2nd hall, z=1st hall

 

from last sentence

2x=9876/3 ==> x=1646

 

from mid sentence

(1/3)y+x=2x ==> y=4938

 

from 1st sentence

4/5(z)=3292 ==> z=4115

 

to get initial y

y-(1/5)z=4115

 

 

[Sabbie]

Actually, what's the point if you are able to solve this maths problem, does it really help the person get a well paying job in real life?

Problem is at P6 level they are not yet taught using simultaneous equations to solve problems so your method cannot be used.

SG Ed system is not t o provide Wholesome Education to our kids.

Its designed to sieve out those who can make it and those who can't.

They have no time and patience and money in their plan to anyone who needs more of it to reach their fullest potential.

For 12 year old, it is easy to them..

 

for us no, because we know too many method liao..

 

sometime the easiest method is the most simple one.
