3rd Annual Mathlympics - 2010 Prelim round

[INNOVATE]

Never heard of this competition. See so many finalists from both famous and neighbourhood schools. Just recall my dd, lazy,careless and not keen in her academics was reluctantly asked to represent her schools in various maths competitions all the way to olmpiad senior category. Never show any comittment still able to win honours for her schools. Till today, regard all her wins as totally underserving compared to manyu other competitors.

The prize presentation for the finalists was this morning. Tao Nan emerged as the top school, with 10 gold, 11 silver and 21 bronze (iirc). Additionally, 2 students from Tao Nan clinched overall champion and overall second respectively. (one of them is me..!)

Congratulations! Are you from GEP?

7 * 5 * 4 * 3 = 420
The 6 and 2 is redundant, since any number which is a multiple of 4 is automatically a multiple of 2; any number which is a multiple of 4 and 3 is automatically a multiple of 6.
Primary schools will probably only teach the listing way to find LCM.

Thank you.

a/n = n/49a

49a^2 = n^2
n = +7a or -7a
