Not sure if P4 have algebra in syllabus already. If not might need guess and check method.

Answer is a) 90 and b) 210

Q33: to answer this q, need to come out with simple table based on thrice number of dog, 1 cat 3 dog 2 cat 6 dog 3 cat 9 dog 4 cat 12 dog 4 and 12 fit in as the difference is 12, so total animals is 16

Hi Kelly I tried using the first method myself last night which is algebra but second equation written salah so did not get the answer!

Salute :) power

4u + 8 = 9u - 12 5u = 20 1u = 4 4x4=16

Guess our time no learn how many U and no so difficult questions :(

That's for sure. We have to learn together with the kids now. Loll..

Have! Cos question said "same" at the end hence u can use =. Therefore 4u + 8 = 9u - 12 5u = 20 1u = 4 Since 4u represents volley balls just sub to get the initial answer loh. 😉 4x4=16

Darren, I beg to differ. The Math kids do nowadays, especially Sec & JC onwards, are nothing compared to what we did... I can prove this to you anytime ☺

No more additional maths ?

U have example ?

Have. But what they're doing now, some topics eg Relative Velocity, P&C, Functions have been removed while Geometry Plane Proofs, Partial Fractions have been added. In terms of difficulty, now is also less daunting than the syllabus B in the 1980s, with the exception of IP curriculum. Where JC Math is concerned, Mechanics have been totally removed, and Further Math is no longer offered (Next year it will be back in some JCs though). I could go on to write an essay lol, but suffice to say what they're doing is less demanding in terms of breadth & depth.

Thanks for info. Wonder if the changes are for better or worst . Read recently that Singapore education are among the best in the world . Parents are struggling to teach our kids the math.

You used the word "education"... that's beyond my pay scale to comment lol. Ask the 2 new ministers 😄

QN something wrong.. It should be Hakim received 5/14 of Lisa Only...and not 5/14 of Fred and Lisa...

Question is faulty. It should be Fred has 2/5 as many as Lisa, which makes the total for Fred and Lisa to be 7u.

I also think so.

Thanks, Izam. I thought so too but not sure if I had missed out on anything.

Thanks, Hariani.

Not at all
