James Ang:

Paper 1 (40 marks, no calculator) would have been completed by now. Is it easy?

DD just called. She said is quite easy this year. If easy, that means mean mark will go up. It w b hard to score high point.

[James Ang]

Paper 2 was quite challenging

[wargame123]

question 29 answer is 28. right

from what my son says the method is as follows
110 minus 1 as the last man is an extra out of the group
then use 109 divided by 4 which gives u 27 r1 as in a group there can be 3 women and 1 men
the remainder of 1 means that in one of the group they have 4 women
then add 1 to 27 as there is still a man at the back
and my son also said that those ppl who put 44 has double counted the man
making it: m w w w m m w w w m m
thus it will have no women in betwwen some of the men

The last question was quite tough… Does anybody know how to do it? Even the top math student in my class was struggling.
