Oh ya... never thought of that, thanks BigDevil! BTW, I just added you onto my buddylist! Well, OK, I won't crack my head over it (maybe fracture it a little :D)

Hi, thanks for all you guys for trying. I copied the q from my girl P6 worksheet. I was also stuck and not able to get the ans.


now waiting for the school to return the worksheet.
kindly help check if the logic below is correct.

After:
cake
[u][u]

cream puff

[u][u][u][u][u]

before

[u][u][45][45]

[u][u][u][u][u][42]

[u][45]=[u][u][u][u][u][42] 2:1


4u=3 ?????

[Muffins]

Hi stuckinratio, but that means that you had 1.5 cakes at the end and 12.5 cream ouffs at the end, and if you add the sold numbers, they don’t "ratiolise" up.

[stuckinratio]

Agreed.


Maybe there is an error in the q as mentioned by some.

But basing on the relationship of the ratios b4 and after ,does the ‘logical’ approach and model make sense though it does not gives a logical ans?

thanks

[Muffins]

pardon. could ya rephrase that sentence. Couldn’t understand.

[stuckinratio]

oops.


wondering if the approach of solving the problem using the end (after the sales ) and comparing the ratio in the manner which ends up an illogical ans of 4u=3 is ok.

[stuckinratio]

mean using the end as a start point is ok

[Muffins]

Yeah, that method’s actually more sophisticated than normal model method.

[stuckinratio]

oh. heard of using cross mulitplication also.


can’t find any example how it’s being done.

how maths have changed since my p6 almost 35 yrs ago. ha ha ha.

That's how I got to 91.5 cake and 45.75 puffs.
