Number Puzzle #5
How many triangles #5
1.) How many triangles are there in this triangle ?
how many triangles in this triangle
Answer: There are a total of 47 triangles
How?
Lets count…
By looking at it, first impression is … its very simple, But mind you! its not that easy !!!
So lets stick to the divide and conquer approach, we will divide this triangle into 3 equal triangles(triangle formed by connecting outer side to the center of the circle) and will count the number of triangles in each part and then by taking two or more parts together.
Number of triangles in one part: 4(non overlapping) + 3(overlapping) = 7 * 3 = 21
Number of triangles by taking two parts together: 8 = 8 * 3 = 24
Number of triangles by taking all three parts together: 2
Thus, total number of triangles in this puzzle are : 21+24+2= 47
Number Puzzle #4
6 – 1 x 0 + 2 / 2 = ?
Answer with Explanation
Given
6 – 1 x 0 + 2 / 2
= 6 – 0 + 1
= 7
So answer to above number puzzle is 7
Number Puzzle #3
IF 11*11 = 4, 12*12 = 9, Then 13*13 = ?
Answer with Explanation
Given
11×11 = (1+1)*(1+1) = 4
12×12 = (1+2)*(1+2) = 9
13×13 = (1+3)*(1+3) = 16
So answer to above number puzzle is 16
Number Puzzle #2
IF 1 =2, 4 20, 6 =42, 9=90, Then 10 =?
Answer with Explanation
Given 1 = 1^1 + 1,
4 = 4*4 + 4 = 20
6 = 6*6 + 6 = 42
9 = 9*9 + 9 = 90
10 = 10*10 + 10 = 110
So answer to above number puzzle is 110
Number Puzzle #1
IF 1 = 5, 2 = 11, 3 = 36, 4 = 150, Then 5 = ?
Answer with Explanation
Given 1 = 5,
2 = 5*2 + (1) = 11
3 = 11*3 + (1 + 2) = 36
4 = 36*4 + (1 + 2 + 3) = 150
5 = 150*5 + (1 + 2 + 3 + 4) = 760
So answer to above number puzzle is 760
How many triangles #4
1.) How many triangles do you see in this image ?
how many triangles do you see in this image
Answer with Solution
Looking at the symmetry, we can divide this triangle in 5 equal parts(square) and we will first count the number of triangles in each part and then number of triangles formed by combining 2 or more parts together.
Number of triangles in one square: 8(non overlapping triangles) + 8(overlapping triangles with middle lines a part of the triangle) =16*5 = 80
Number of triangles by taking two squares(one middle and one other) at a time: 4*4(there are four such combinations) = 16
Number of triangles by taking (only) three squares(one middle and two others) at a time: 4(all squares should be a part of the triangle) *4(four such combinations) = 16
Number of triangles by taking 4 squares together: 2 *4(four such combinations) = 8
Thus total number of triangles = 80 + 16 + 16 + 8 = 120.

How many triangles do you see
There are a total of 84 triangles

Lets count…
Looking at the symmetry, we can divide this triangle in 4 equal parts(square) and we will first count the number of triangles in each part and then number of triangles formed by combining 2 or more parts together.
Number of triangles in one square: 8(non overlapping triangles) + 4(overlapping triangles with middle lines a part of the triangle) =12
Number of triangles by taking two squares at a time: 6(try a little harder, you will fidn these) * 4(there are four such combinations) = 24
Number of triangles by taking (only) three squares at a time: 1(all squares should be a part of the triangle) *4(four such combinations) = 4
Number of triangles by taking all squares together = 8
Thus total number of triangles = 12*4 + 24 + 4 + 8 = 84.
How many triangles #2
1.) How many triangles are there in this picture ?
How many Triangles are there in this picture
There are a total of 92 triangles
How?
Lets count…
Looking at the symmetry, we can divide this triangle in 4 equal parts(square) and we will first count the number of triangles in each part and then number of triangles formed by combining 2 or more parts together.
Number of triangles in one square: 8(non overlapping triangles) + 8(overlapping triangles with diagonal a part of one of the side) + 3(diagonal is perpendicular to one of the side of the triangle) =19(You can get it correct after a little hard try)
Number of triangles by taking two squares at a time: 3(common side of square is perpendicular) * 4(there are four such combinations) = 12
Number of triangles by taking three squares at a time: 1(all squares should be a part of the triangle) *4(four such combinations) = 4
Number of triangles by taking all squares together = 0
Thus total number of triangles = 19*4 + 12 + 4 +0 = 92.
How many circles?
Count the number of circles in the image below.
how many circles do you see in this picture
There are a total of 17 circles.
How?
1 black circle in the middle(easily visible to all)
Now move a little away from the screen(16 more circles will be visible easily).
Thus, there are a total of 17 circles.
