1. ## Re: hee hee need help in Pri 4 Maths (again)

I remember this type of questions in P4, but they were rare, and usually we either skipped it or just brute force the answer. But, i cannot remember it coming out in test or exam.... I remember this usually comes out in those kind of primary sch math olympiads etc. Maybe its for those GEP people? Cause i was in GEP, and i distinctly remember seeing this kind of questions.

It's logic, it's not much math. But maybe that's just me.
The question maybe there to sniff out that distinction student from all the 'A' student

remember reading some article on yahoo, Singapore education system churn out large percentage of good students, while the American education system churn out more genius than Singapore system but kills off the main bulk of the students.

guess Singapore is trying to inject some way to filter out possible genius student from the good students.

there is no such single digit greater than 9 right?

why can't H be double digits? like 88, 73, 90? u mean to say it must be single digit even if the question didn't say so? if yes then ok lo. ahhahaha... nv attempt such questions before.

i thought i was good with logic then this came busting it down!

Guess this is "who is smarter than a 5th grader"!

after thinking about it for 10 minutes i gave up.

if i am the person attempting the question. this is what i will write.

What is K (0 to 9)?

Since no numbers are given and that the alphabets in the problem can be any numbers from zero to infinity. I can neither deduce any possible solution nor make any sensible assumptions. Even if I copy the answer from my friend sitting next to me i will have only 10% chance of getting it correct, which is no better than me even wild guessing here.

The best way to find the answer would be to ask 9 another friends, and all of us write a different answer. From there we will know K equals to what when the paper comes back. The only assumption i am can make here is that K = any value from 0 to 9, and is a whole number.

I'm supposed to be the Maths geek in the club but I'm too tired to think already so I'm glad my Physics sidekick figured out the answer.

Thanks, allenleonhart. And to everyone else who's an inner geek, can u all not be shy2 to join the geeks group??
