a. $12, or 1200C
b. 1.026kg
[quote=Pinkfellow post_id=2040092 time=1633072706 user_id=137321]Helen and Ivan had the same number of coins. Helen had a number of 50-cent coins and 64 20-cent coins. These coins had a mass of 1.134 kg. Ivan had a number of 50-cent coins and 104 20-cent coins .

(a) Who has more money in coins and by how much?(2)

(b) given that each 50-cent coin is 2.7g more heavier than a 20-cent coin, what is the mass of Ivan’s coins in kilograms? (2)

[/quote]Part (a):
Given that they both have the same number of coins, and Ivan has 40 more 20 cent coins than Helen, this means that both Helen has 40 more 50 cent coins than Helen, also meaning that she has more money.
Helen has 40(50C-30C)=$12 more than Ivan

Part (b)
Since Helen had 40 more 50 cent coins than Ivan, therefore her coins are (40x2.7g)=108g heavier than Ivan's coins. Then, simply subtract 108g from 1134g, which equals to 1026g or 1.026kg

May i know what are the subjects stand for:
1) ACC (O)
2) ACC (E)
3) Science lab ( O)
4) science lab (E)
5) HCL (O)
6) HCL (E)
7) TRPI (O)
TRPI (E)
9) LSP (O)
10) LSP (E)
11) PE (O)
12) PE (E)


Why subjects come with \"O\" and \"E\" ?

\"O\" stands for odd weeks, which are days 1-5, which is next week, as this week is considered week 0. \"E\" stands for even weeks, which are days 6-10. There was a reply to another question regarding the timetable earlier on that said that the 10 day timetable was a temporary one, which is false, as the timetables are always 10 days.

Hi, can anyone advise the size of next year's Sec intake and the estimated class size?

It should be around 300. Apparently there wouldn’t be a J class next year and there would be 36 students in a class with 28 students in I class or maybe h class, I’m not too sure how many SBGE classes there will be.

Is there a class that is dedicated to STEM?[/quote]

1A-1H are normal classes, 1I is for students who scored well for Chinese in PSLE or Dsa bilingualism. 1J is for students who do well for math and science in PSLE and I think also dsa science and math. Only 1I and 1J have stem
