Does anyone know the answers to question 30
A number of children are standing in a circle. They are evenly spaced and the 7th child is opposite the 18th child. How many children are there?
Perimeter of a shape - can't draw it on here but i anyone has the paper, I think there needs to be more info for the question to be answered
Q36: ignoring the 7th and the 18th child, there are 10 children located in positions 8 th to 17th inclusive and the same number for the other half of the circle. So in total there must be 22 (10 +10+2 now includes the 7th and 18th child) in the circle.
On the move at the moment and font have the 2010 paper with me so can't help with q36 , sorry!
