MCQ Test: Images and Figure Counting - 2 - Bank Exams MCQ

The triangle 6 shown in figure and another is ADB,ACB, BDC,ADC, so that total number of triangle is 10

8+3+3+2+2+4+3+2+1= 28

The below figure shown the total no. of triangles is 8+8+2+6+4=28

3+3+3=9 triangle 

Triangle ABD +Triangle ADC =2

Same as 2+2+2=6

And Triangle ABC=1 

So that total no of triangle in this figure is 9+6+1=16

In the above figure it consist 8 triangle so that no. of square is 3 so that total no. of triangle is 8 ✖ 3=24

and 4 triangle shown in question figure so that answer is 24+4=28 

First mark each rectangles 1, 2 and 3 after we can cube of 1 +8+27=36 we get the answer

Small triangles = 5
Triangles formed by combination of 2 triangles = 3
Triangles formed by combination of 3 triangles = 1
Thus, total triangles = 5 + 3 + 1 = 9

Smaller triangles = 6
Triangles at the diagonal of the square = 4
Triangles formed by combining 2 triangles (at the right) = 1
Triangles formed by combining 1 triangles and 1 quadrilateral (at the bottom) = 1
Triangles formed by combining 3 triangles = 1
Thus, total triangles = 6 + 4 + 1 + 1 + 1 = 13

Smaller triangles = 6
Triangles formed with combination of 2 triangles = 2
Triangles formed with combination of 3 triangles = 2
Larger triangle = 1
Thus, total triangles = 6 + 2 + 2 + 1 = 11

Larger triangles = 3
Triangles formed with color combination (blue+red) , (red) and (red+yellow) = 3
Thus, total triangles = 3 + 3 = 6

Smaller triangles = 7
Triangles formed at diagonals of smaller square = 4
Triangles formed at diagonals of larger square = 4
Thus, total triangles = 7 + 4 + 4 = 15

Smaller triangles = 6
Triangles formed by combination of 3 triangles = 2
Larger triangles (at the diagonals) = 4
Thus, total triangles = 6 + 2 + 4 = 12

Small triangles = 8
Triangles formed by 2 triangles = 2
Triangles formed by 2 triangles and one trapezium = 2
Larger triangles = 2
Thus, total triangles = 8 + 2 + 2 + 2 = 14

Small triangles = (AEF, AEG, GDH, CFH), (IEK, IFL, JLH, JKG), (IOK, IOL, JOL, KOJ)
Big triangles = IKL, JKL, IJK, IJL
Thus, total triangles = 16

Smaller triangles = (ABC) , (ACD) , (ADE) , (FGJ) , (GHJ) , (HIJ)
Triangles made by combination of 2 triangles = (ABD) , (ACE) , (AFG) , (AGH) , (AHI) , (FHJ) , (GIJ)
Triangles made by combination of 3 triangles = (ABE) , (FIJ)
Triangles made by combination of 4 triangles = (AFH) , (AGI)
Triangles made by combination of 6 triangles = (AFI)
Thus, total triangles = 18

Small triangles = 6
Triangles made by combining 2 small triangles = 3
Triangles made by combining 3 small triangles = 6
Large triangles = 1
So, total = 6 + 3 + 6 + 1 = 16

Smaller triangles = 12
Triangles formed with 2 triangles = 4
Larger triangles (combining triangles at the centre) = 4
Thus, total triangles = 12 + 4 + 4 = 20
