This is a cool brain teaser in which one has to find the missing number in the series.

15. Which will be the missing number in this series?

5, 10, 17, ?, 37, 50

16. IF

1 + 2 + 3 = 343

2 + 3 + 6 = 666

3 + 4 + 5 = 985

Then

2 + 2 + 3= ?

__Answer to Simple Math Riddles: Brain Twisters__

1.

The answer is 30.

IF

AxBxC = D Then the answer is Cx5. Other digits A and B are ignored.

2.

The answer is 855. If AB+CD = E then answer is (A+B)CD i.e (4+4)55 = 855.

3.

The answer is 3612. If A + B = C then C = (AxB)(A+B) i.e. (6x6)(6+6) = 3612.

4.

The answer is 32.

IF A+B = D Then the Answer is 4*(A+B).

5.

Answer is 514

IF A x B x C = D then D = (A*B)BC

6.

Answer is 41

IF A+B=D Then Answer D drives from reverse the result of AxB.

7.

The answer is 3.

If A+B = C then the answer to this brain riddle is A/B i.e. 12/4 = 3.

8.

The answer is 6.

IF AB + C = D Then the answer is got from BA-C ie. 15-9 = 6.

9.

The answer is 16. If ABxCD = E Then E = A+B+C+D.

10.

The answer is 1610. If A+B = D then D = (AxB)(A+B) i.e. (2x8)(2+8) = 1610.

11.

The answer is 49. If ABCD = E then E = (A+B)(C+D) i.e. (1+3)(4+5) = 49.

12.

The answer is 206. If abc x def = g then g = (a+b+d+e)(c+f).

13.

The answer is 12. If A B C = D then D = C - (A+B) i.e. 24 - (5+7) = 12.

14.

The answer is 18. This one was very simple. Just divide the sum obtained by 2.

15.

The answer is 26. This is Simple series with a difference in number 2 more than the difference in previous numbers. So the difference starts with 5 and increases in the series 5 7 9 11 and 13.

16.

The answer is 643. If A+B+C = D then D = (Ax3) (Bx2)(Cx1) i.e. (2x3) (2x2)(3x1)=643
