Question:
The ratio of Eric’s money to Kim’s money was 3 : 1. After Eric gave Kim $60, the ratio of Eric’s money to Kim’s money became 3 : 5. How much did Eric have at first?
———————————————————————————————————–
Solution using the Storyline-Balance Method:
E : K
At start: 3u : 1u
Story: – 60 + 60
At end: 3u – 60 1u + 60
Final ratio: 3 : 5
So 5 sets of (3u – 60) = 3 sets of (1u + 60)
15u – 300 = 3u + 180
15u – 3u = 180 + 300
12u = 480
1u = $40
So at first Eric had 3u = 3 x 40 = $120
Ans: $120
Note:
The above is just one method. Another method requires you to notice that in the above problem, the total number of units remain the same as it is an INTERNAL TRANSFER or TOTAL UNCHANGED situation or concept. However, using the Storyline-Balance method, you don’t need to know what has been unchanged.

Was A. Math Paper 1 (2015) difficult?
Yes, according to some students. Some said it was “harder than expected”. One couldn’t do Q4 properly and another gave up on Q6. These are some of the chatter that reached me. Well, if you think you had done badly in P1, then please be more careful tomorrow. And DO NOT PRACTISE ANY A.MATH TONIGHT.
Anyway, even if you didn’t too well in A. Math, you still can get A for math in JC, provided you start early. So if you intend to go to JC and take up Math (H2 or H1), and your sec math is always around A2-B4, then I would encourage you to attend our JC Math Headstart or Bridging classes this Nov or Dec. Please remember that IP students have already learnt some JC Math in Sec 4, so you’d have some catching up to do even if you had done well in any O-Level Math.
Our JC1 H2 Math Headstart classes will commence on Sun 15 Nov or Sat 21 Nov. You can find more details here: Our JC & Secondary Headstart Programmes 2015-2016. “Early bird” sign-ups will of course be given discounts. You can also sms your queries to 97860411. Thank you.
ALL THE BEST FOR TOMORROW!
Heard O-Level (2015) Math Paper 2 was “easy”.
I smsed a few tutees about Math Paper 2, and the responses were:
- “easier than paper 1”
- “much better than p1 yay”
- “got all correct except Q7b”
- “finished in 1.5 hrs”
Okayyy, I get the message. So all of you are going to get A1 for p2 but when combined with p1 you are going to get A2? Just joking. What is more certain is that since p2 is easy, the examiners will “find fault” with your answers in any way they can – presentation, d.p., sig fig, labelling on graphs, units, reasons for trigo etc.
Anyway, pls focus on A. Math tmr. Get some sleep.
Rgds,
Ilyasa

Heard O-Level (2015) Math paper 1 was “hard” or “unusual”.
A tutee from Crescent Girls’ said it was “harder than in past years”. And already there is someone who found my website today using the search phrase “am i eligible for jc when fail o level maths”.
My daughter said it was “tedious” and had “ugly” numbers. But she admitted it was easier than her prelims. Anyway, please remember that Paper 2 isn’t over yet. Even if you had lost today’s battle, you have not lost the war against Math.
Anyway, all the best to you if you are doing O-levels this year!

Ilyasa
