This question is driving me nuts~ could anyone help me?
hakim and suresh had some money in the ratio of 13:8. When they each received $133, Hakim will have 4 times as
much money as Suresh. How much did Hakim had at first?

Don't go nuts, the solution is here :)
hakim had 13u
suresh had 8u.
later Hakim had 4 p
Suresh had 1p.
difference between them is unchanged
1p = 8u  133
3p = 5u (the difference between boys)
24u 399 = 5u
19u = 399
1u = $21
Hakim had $21 X 13 > $273
Hope this helps!

I used your answer to subsitute back into the question and it does not seem to be correct. Your answer $273 is only correct if we changed the question instead of 'received $133' to become 'gave out $133'.

I also seems to have problem with this question. The answer does not make sense if subsitute back to the question.
Meaning, if
H has $273 at first, that means S will have $168.
If each received $133, that means H has $406 and S will have $301 at the end.
Does not satify the condition of H having 4x more. Right?

Hi, I believe the question 'as is' is plain wrong. I misread it, sorry, but I think that is the only possible interpretation, anyway.

Dear <ashlene>, <khengsin>, <Sexyviper>, <nisalam> and all,
I have done this question last year and had explained then that the question should have been rephrased. Instead of "When they each received $133 ..." , it should read as "When they each gave away $133 ...". then <nisalam>'s solution will fall into place.
Similar thoughts were shared by <khengsin> and you are correct. Thank you.
My solution was done using <Unchanged Difference> concept and I can tell / realize the mistake in the question at that moment. (note: my solution is on p41 and last posted by <jennefer_06> on Apr 11, 2012. Title: Pri 5 problem sum)
Occasionally there are questions wrongly set as a result of typo errors (as recent as in a couple of SA1 2012 papers). The same goes for <Answerkey> too.
It is important and essential for the viewer to learn and understand the concept and method of working, despite the occasional hiccups / flaws in the question and/or answerkey. The same goes for the clarity of the question itself too.
Putting back <nisalam>'s answer into the question, we have ...
H : S
13 : 8
H: 273
S: 168
Based on my 'rephrased' statement, each gave away $133, we have ...
H: 273  133 = 140
S: 168  133 = 35
H : S
140 : 35
4 : 1
=======
Trust this helps.
Thank you and all the very best in your SA1,
Edward
