PapayaDad:

Champion play most matches. (actually 2nd place, 3rd place, 4th place all play the same number of matches).


Anyway, at first champion was in a group with team A, B, and C. And champion played once against A B and C. So played 3 matches liao.

Then round of 16 - champion play 1 match and advance to round of 8
champion play 1 match and advance to round of 4
champion play 1 match and advance to round of 2 (final).
champion play 1 match (final).
Total number of matches played is 7

Does it mean 2nd place also played 7 rounds, and 3rd and 4th place played 6 rounds?

Hi all, thank you so much for providing the solutions. The answers are correct. The length of triangle is 5cm (I also thought is finding the perimeter of the big triangle!) and number of matches is 7. Thank you for helping!

Hi all, appreciate your help on the below question:


Two excavators were deployed to dig earth. Excavator A, working alone, takes 20 days to complete the project. Excavator B, working alone, takes 30 days to complete the project. The whole project was completed in 16 days, using both excavators, but in between Excavator A stopped digging for 3 days and Excavator B stopped digging for a number of days. How many days did Excavator B stop digging?

Thank you!

Hi, I am looking for a piano teacher for my 5 year old girl, would like to hear from anyone whose private teacher practice like outside piano centre - for a certain month the teacher will only teach for 2 lessons but we have to pay for 4 lessons? Usually this is practiced by piano centre. But practice by home based private teacher, is it common? Thanks.
