#53 - 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
#54 - 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.
#55 - Replace Shape Puzzle

#56 - 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
#57 - 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
#58 - 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)
#59 - Fun Algebra Puzzle
The following alphametic has only one solution. Can you find it?
