"In the Balance"
Give This Brain Teaser One Minute's Effort
Scales 1, 2 and 3 are perfectly balanced. Calculating the value of each scale's triangles, circles. squares, and diamonds, determine how many triangles it takes to balance scale 4.
The answer is One Triangle.
Scale 1 shows that two triangles equal one circle, so six triangles equal three circles.
Since Scale 2 shows that three circles equal three squares, six triangles equal three squares.
Scale 3 shows that one square equals four diamonds; two triangles equal four diamonds.
One triangle then, equals two diamonds, and would balance scale 4.
