Answer of these Mind Twister Math Questions is given below. I have hidden the answers to avoid inadvertently looking at the answers. To read the answer of particular math riddle, select the text between two numbers.
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
A1.  6
            We have to use 5,3,3,3 to get 6
             So applying mathematical operations we get,
             5x3- 3x3= 15-9=6

A2. 36
We have to use 8,8,3,3 to get 36
Cube root of 8 = 2, so using cube root fot both 8 we have 2x2x3x3=36.

A3. 123
Explanation:
Its last digit and then next digit is number of zeros.

A4.  0,
using DMAS
3÷3=1X2=2+3=5-5=0

A5.  125
PATTERN IS  WE= place value of W+ place value of E= 23+5=28,
ARE = 1+18+5= 24, PUZZLER= 16+21+26+26+13+5+18=125

A6.      47,95,383
            23X2+1=47, 47X2+1=95, 191X2=1=383,

A7. 6
        24X3=18  is as below :
        2+4=6x3=18,  36x2=18 as 3+6=9x2=18, similarly  12=1+2=3x6=18.

A8.          I  N,     M    R,     Q   V,    U    Z,   Y     D
              9  14 ,    13   18,    17  22,   21  26,  25    4
  First alphabet is place value of first alphabet of last term +4, second alphabet= place value of second alphabet of last term + 4

A9.   15, 72
Required number= first digit x last digit+ second digit x third digit

A10. 117,  required number=  1 and sum of digits

Example  5+6 = 111
