Math Puzzles with Solutions: Solve Logical Math Riddles:

Question:

It is a simple math puzzle that needs a little logic to solve. Three numbers in first equation are separated by a comma & they are equal to 10. So we need to find a logic that verifies the fact: how these numbers are equal to 10. The logic is to multiply first 2 numbers & add the third number.

Let’s solve first equation

3, 2, 4 = 10

3 x 2 + 4 = 10

6 + 4 = 10

10 = 10

L.H.S. = R.H.S.

Hence first equation satisfies our logic. Now we are using this logic in the second equation & checking its validity:

4, 3, 5 = 17

4 x 3 + 5 = 17

12 + 5 = 17

17 = 17

L.H.S. = R.H.S.

Second equation also gives correct result. Hence I think this logic is correct but as we have more equations so let’s try this logic in those too.

5, 4, 6 = 26

5 x 4 + 6 = 26

20 + 6 = 26

26 = 26

L.H.S. = R.H.S.

We can clearly say, this logic works. Final check:

6, 5, 7 = 37

6 x 5 + 7 = 37

30 + 7 = 37

37 = 37

L.H.S. = R.H.S.

Now we have an unknown. Let’s find it out by applying the same logic:

7, 6, 8 = ?

7 x 6 + 8 = ?

42 + 8 = ?

50 = ?

Hence unknown number (?) is equal to 50.

Answer = 50
