Hi. I’m a secondary 4 student. I scored an A* for maths back then. However, it is PERMITTED to use algebra in the PSLE. My sister taught me algebra and simultaneous eqns back then and I used those methods to solve the problems in PSLE. During my prelims, my teachers had no qualms about it and they would mark my methods right. Hence, I went ahead to use algebra and simultaneous eqns during the PSLE exam and I certainly did not do badly.

So cheers! Algebra is actually allowed.

heeys! i am not showing off or anything. I am not good in maths but this qns. is seriously simple. I took a while lyk not even 5 mins to figure out. It does nt have to be done with algebra. Just a few steps:
156 - 72 = 84
4:1 = 3u diff. = starting diff.
starting diff = 84
rice sold = 72 - (84/3) = 44kg.

So simple! even my fwen who only got 26 for maths knows how to do it.
anyways. using algebra will also get marks. lols.

I am going to give PSLE this year(2008).This is question is a bit confusing but i know how to solve it. Since, they sold an equal amount of rice, the original difference remains the same. The difference is 156-72=84kg. Now the ratio difference is 4-1=3units.Now, that 3units is = 84 kg. Sho B now has left 1unit so it has 84/3 = 28 kg. To find out the rice sold , 72kg(what it had before)-28kg(what it has now)=44 kg. I hope this solves your queries. And one more thing, you CAN USE ALGEBRA.YOU WILL NOT GET A ZERO

This question is sooooooooooooo simple just look at the EQUAL word you kow how to do already. Besides I think that the answer should be 88kg becoz they say find the amount of rice sold by the SHOPS. Anyway I am Jajax and I am in P5 this year. Scared abt PSLE next year!

some of the answers do not sounded logical…

A had 156kg, B has 72 kg.
Same amount of rice sold, hence the deduction from above will be same.
After sales, ratio is 4:1, hence for the 3 parts it is (156-72)kg = 84kg, hence each part is 28kg.
They left a total of 5 parts = 28 x 5 = 140 kg.
As a result, amount of rice sold = (156 + 72) - 140 = 88kg.

Some students say the question is hard but as long as u learn the effective method u will know how to do it in a minute.Some methods are like…
(Constant Diff.)for these type of questions . To know this method…
find it out from your teachers…they are COOL! HEY ! be serious PSLE…
REMEMBER >CONSTANT DIFF.!
