Q:

Can you crack the code?

394  is the code to unlock the key.

If you take the second statement, 7 is incorrect from the first statement and 1 is incorrect from the fourth statement. Hence 4 is correct, but not on the second place. From the third statement, 4 is not on the first place. Hence 4 is on the third place.

From the fifth statement either 6 or 9 is correct. But combining it with the third statement, 6 is incorrect. Hence along with the first statement, 9 is correct and on the second place.

From the third statement, 3 is correct and on the remaining first place.

Q:

Can anyone solve this in 20 seconds?

3 + 5 + 6  = 151872

3x5, 3x6, Rev of (3x5 + 3x6 - 6)

5 + 5 + 6  = 253094

5x5, 5x6, Rev of (5x5 + 5x6 - 6)

Similarly,

9x4 = 36

9x7 = 63

So 36 + 63 = 99

From 99 - 7 =  92

Reverse of 92=29

Hence, 9 + 4 + 7 =  366329.

Q:

Can You Guess The Missing Numbers In The Given Math Puzzle?

 A) B) C) D)

Explanation:

Let the missing numbers be x, y, a and b

x + y = 8 ---- (1)
a - b = 6 ---- (2)
x + a = 13 --- (3)
y + b = 8 ---- (4)

2x + a + y = 21 --- From (1 & 3)
a + y = 14 ----  From (2 & 4)

Substitute (2 & 4) in (1 & 3)

2x + 14 = 21
2x = 7
x = 3.5

From (1) ---> 3.5 + y = 8
=> y = 8 - 3.5 = 4.5

a + y = 14 => a = 14 - y = 14 - 4.5 => a = 9.5
From (4) ---- y + b = 8 => b = 8 - y = 8 - 4.5 = 3.5

Hence,
x = 3.5
y = 4.5
a = 9.5
b = 3.5

Q:

Find the logic and solve this mathematical puzzle?

 A) 112 B) 72 C) 127 D) 144

Explanation:

In the given puzzle, the logic is

2 + 3 = 10 => (2 + 3) * 2 = 10

6 + 3 = 54 => (6 + 3) * 6 = 54

8 + 3 = 88 =>  (8 + 3) * 8 = 88

Similarly,

9 + 7  => (9 + 7) * 9 = 16 x 9 = 144.

Q:

Break the logic behind the given mathematical puzzle?

 A) 7 B) 8 C) 11 D) 13

Explanation:

In the given puzzle,

The logic is in the format of lets say, a/b

In that case b doesn't matter, because

2/2 = 1,

6/5 = 6/2 = 3,

10/11 = 10/2 = 5

This means that equation is a/2

So 16/19 is equal 16/2 = 8.
