PSLE bar has been raised too high

Let me try deconstructing it :D

($5+$2)x = $511.
x = $511/$7 = 73 pieces

2 pieces of $5 notes were exchanged for $2 notes of similar value = $5 notes - 2, $2 notes + 5

Original number of $2 = x - 5 = 73 - 5 = 68.

Original number of $2 = x - 5 = 73 - 5 = 68.

Alternatively,

the multiplication factors of both $5 and $2 are constant. The only thing different is the total value. $5 is 2.5 times that of $2. So the total value of $5 notes should be 2.5 units while for $2 notes it's 1 unit. Therefore,

2.5+1 = $511
3.5 = $511
1 unit (which is the total value of $2 notes) = $511/3.5 = $146
Number of $2 pieces = $146/$2 = 73

2 pieces of $5 notes were exchanged for $2 notes of similar value = $5 notes - 2, $2 notes + 5

Original number of $2 = 73 - 5 = 68.

I helped out at a hawker stall in my teenage years. I did struggle on a few occasions then when customers pay more than I expected in order to get rounded sums of change e.g mixed veggie rice $2.70 knn customer gives $10.70 instead of $10 that most customers usually give and make me blur. Not only did I have to calculate, I also had to find a $1 coin for him. :rolleyes:
 
Wahahahaha!!! Tonychat the utter dumbfuck giving an "intelligent" answer!!!!

Add one to each then reduce the adam to 300 and ben to 100. Then you get it. Or no need to add one just reduce it.

sorry, intially 75pcs of $5 notes. too sleepy and type wrongly. 68 x $2 and 75 x $5 = $511

Yes correct
2x + 5x = 511
x = 511/7
x = 73
Beginning $2 note>> 73 - 5pcs = 68 pcs
Beginning $5 note>> 73 + 2pcs = 75 pcs

My time life was simple...SIngapore was barren land, where the Caraboas roam, there was "cluck cluck here, Cheep, Cheep..there". Our Arithmetic was easily understood, Ali have 5 oranges, 6 apples & 4 pears, he gave Ah Lan 2 apples, 3 oranges & 1 pears, Muthu gave Ali, 6 oramges, 2 pears..how many fruits does Ali have? The best part of this, that many who passed & went on to become, Colombo Plan Scholars etc.. and become Perm Sec..etc earning obscene salaries.. all this, when we were a barren land..

ha ha ha ha
