There's a hot quiz show in the US called "Are you smarter than a 5th grader?".
Well, in this version called "Are you smarter than a P4 student?", I fail miserably! Monica posted these two questions, from a Pri4 assessment book, and I tried for hours and still can't solve it. What's wrong with me???? It's like there's this mental block stopping me from seeing it; I bet you when I see the solution, I'm gonna whack my head and ask "why the heck couldn't I see that, it's so bloody simple" while mouthing all kinds of expletives directed at myself. ARRGGGGHHHHH!!!! STRESSSSSSS!!!! I tell you if I'm in Singapore's education system, I'd probably be mental by now. How do you guys do it? Errrr, maybe some of you guys are already mental, you just don't know it...hehehehehehe....
Oh Mon, in case you didn't see my comment, please don't provide the solution first. Pretend I'm just a kid and I don't know how to do it, how would you prod me in the right direction? How would your 3 tips for models apply in these questions?
1) Jack and Ali are given a certain number of maths problems to solve. If Jack solves 3 problems and Ali solves 1 problem every minute, Jack will have 12 problems unsolved when Ali has finished solving all his problems. If Jack solves 1 problem and Ali solves 2 problems every minute, Jack will have 42 problems unsolved when Ali has finished solving all his problems.
a) How many problems were given to Ali?
b) To finish solving the problems at the same time as Ali, how many problems must Jack solve every minute if Ali solves 4 problems every minute?
So Brian got back at 7am today, had a bath and wanted to use the computer to play his school's online math programme, First in Math. I said Hold on! Hold on!, do this first. So he did and got the answers. I don't understand the second part of the work though, how he got 16.
2)There are 500 male and 200 female employees in Company A. There are 400 male and 600 female employees in Company B. Some employees are transferred from Company A to Company B. After the transfer, the number of male employees is the same as the number of female employees in Company B and the number of male employees is twice the number of female employees in Company A. How many female employees were transferred from Company A to Company B?
Brian got this right but by guess-and-check!
