Paper 1 was easy, except one tricky qn no 29. -
Paper 2 was quite challenging

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 -
How on earth do you do the last question for paper 2?
