The solution of simple mathematical reasoning is that a circle plus a triangle equals 27, three circles plus five triangles equals 105. What are a circle and a triangle respectively?
A circle+a triangle =27
3 circles +3 triangles =8 1
Three circles plus five triangles equals 105.
∴2 Triangle = 105-8 1
Triangle = 12
Circle =27- 12= 15
