Place the numbers 1 - 12 in the twelve circles below so the sum of each side of the triangle is 36. I will give you a head start by placing some of the numbers for you. (The numbers may be used once only).
12+7+3+x+10=36 x=36 - (12 + 7 + 3 + 10) x=36 - 32
x = 4
The answer is 4 .
1) 6 , 5 , 43.2 2) 5 , 4 , 31.25 3) 4 , 3 , 21.33 4) 3 , 2 , ?
