#5 - Lateral Thinking Height Of Red Bar Puzzle

Can you determine the height of red bar with the help of information provided in the picture below?

Lateral Thinking Height Of Red Bar Puzzle

8m

From green bar, we can deduce that
the height of vertical bar = 2/3 of uninterrupted shadow length of the bar.

Therefore shadow of 6m of red bar indicates the height of 4m.
The remaining red bar casts a direct 1:1 vertical projection on the wall.

Therefore total length = 4m + 4m = 8m.


#6 - Logic Equation Puzzle

Can you identify the logic behind the equation below and solve the puzzle by completing the equation?

12 + 13 + 7 = 1
15 + 16 + 11= 2
17 + 18 + 16 = ?

4

Logic Used: Sum the numbers and then subtract the two digits to get the desired answer.

12 + 13 + 7 => 32 => 3 - 2 => 1
15 + 16 + 11 =>42 => 4 -2 => 2
17 + 18 + 16 = 51 => 5 -1 => 4

#7 - Make Equation Correct Riddle

Can you replace each alphabet with the number (1 - 9) to make below equation correct ?

AB * C = DE - F = GH / I

39 * 1 = 45 - 6 = 78 / 2

AB - C = DE / F = GH * I can be solved as
A = 3
B = 9
C = 1
D = 4
E = 5
F = 6
G = 7
H = 8
I = 2

So below equation can be solved as:
AB - C = DE / F = GH * I
39 * 1 = 45 - 6 = 78/2
39 = 39 = 39.


#8 - Roman Number Equation Problem

Considering below equation holds

V + II - VI = 10
IV - X + VIII = 20
IV - VII + VI = 30

Then, I + II + III = ?

60

V + II - VI = 10
=> I = 10

IV - X + VIII = 20
=> II = 20

IV - VII + VI = 30
=> III = 30

I + II + III = 10 + 20 + 30

#9 - Replace Question Mark Equation

Can you replace question mark to make the below equation true ?

16 ? 14 ? 4 ? 6 = 62

16 14 / 4 + 6 = 62

#10 - Answer Fast Equation Riddle

If
20 % 5 = 24

21 % 7 = 33

42 % 6 = 67

Then;

66 % 6 = ?

1211
The number on the right side is formed as (sum of digits of the 1st number)(number1/number2)
example,
20 % 5 = 24 (2+0)(20/4)
21 % 7 = 33 (2+1)(21/7)
42 % 6 = 67 (4+2)(42/6)

Simillarly,
66 % 6 = 1211 (6+6)(66/6)
