I have couple of question from Magdalen private school maths past paper, is there any trick or simple way to solve it rather than Trial and error?Q1)
Place one of each of the numbers 1,2,3,4,5,7 in a region of the diagram below so that the
total in each of the circles is the same. The number ‘6’ is correctly placed as a hint.
I don't know how to insert the diagram in here so i put the link to the past paper (Q22)
The link to the paper is:http://www.mcsoxford.org/resource.aspx?id=8878Q2)
Insert the symbols +, +, - , × , × into the boxes(dotted line) below
to make a total of 33. You must use all of the symbols in the list.
