## Answer to Simple Math Riddles: Brain Twisters

1.
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.
IF A+B = D Then the Answer is 4*(A+B).

5.
IF A x B x C = D then D = (A*B)BC

6.
IF A+B=D Then Answer D drives from reverse the result of AxB.

7.
If A+B = C then the answer to this brain riddle is A/B i.e. 12/4 = 3.

8.
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
