Puzzle Questions

Find solution of the following puzzle question:

1 + 3 = 2

2 + 6 = 4

3 + 9 = ?

Q) Given:

1 + 3 = 2

2 + 6 = 4

Required:

3 + 9 = ?

Solution:

The above puzzle question does not follow math rules. Hence it’s a logical thinking puzzle. So what is a logical puzzle?

Maths Puzzles:

Maths puzzles are of different nature. Some of the math puzzles can be solved by applying algebra, others need you to solve equations, permutations & combinations. There are also logic riddles which need some sort of logic to solve.

In this category we have mathematical puzzles which require some kind of math to solve, like: algebra, equations, permutation and combinations.

Logical riddles are included in mathematics genre. These questions test the mind power of solver & inspire them to think harder. Such puzzles at times need complicated math equations, they may need deep thinking too.

We provide maths puzzles with solutions that help logical thinking. You can find a logical puzzle below but it is very easy to solve. There is no complicated calculations & everything required is available. You just need to focus on the question & check out what happens.

For example: we consider a puzzle question which says that:

If NIGHT = 13246,

then TIN = ?

Now we need to apply logic because mathematics laws are not used in above equation. It is based on pure logic such as.

N = 1

I = 3

G = 2

H = 4

T = 6

Now, TIN = ?

From above, we can write:

T = 6

I = 3

N = 1

Hence, TIN = 631

Enough explanation, now we need to solve our main question:

1 + 3 = 2

2 + 6 = 4

Then

3 + 9 = ?

It is a logic puzzle because it does not follow any math rules.

1 + 3 = 2

4 = 2

Hence, we need to divide 4 by 2 to get 2.

So use the same logic in below equation.

2 + 6 = 4

8 = 4

8 / 2 = 4

Hence our logic is correct.

Now solving the last equation.

3 + 9 = ?

In this equation we have an unknown

3 + 9 = ?

12 = ?

Divide 12 by 2

= 6 (Answer)

Hence, unknown number is equal to 6 & this is our answer.
