      5  =  40
      4  =  28
      2  =  ?

A: 2 X 5 = 10

 {The multiplier numbers are in the order of 11, 10, 9, 8, 7, 6, 5 (missing 3x6=18)}

Q: OND  =  11
      UES   =  22
      EDN  =  33
      HUR  =  44
       RID  =  55
THEN,
     UND  =  ?
A: MONDAY = 11, TUESDAY = 22, WEDNESDAY = 33, THURSDAY = 44, FRIDAY = 55, SATURDAY = 66, and SUNDAY = 77

 Q: What goes into the question mark based on the following rule?

                2 - 5 - 5 - 4 - 5 - 6 - 3 - ?

 A: 7 (SEVEN)

Take number 1 to 8. Write them in digital formats

You need 2 lines to make 1, 5 lines to make 2, 5 lines to make 3, 4 lines to make 4, 5 lines to make 5, 6 lines to make 6, 3 lines to make 7, 7 lines to make 8.

Q: Find the missing number in the series?
     3  2  =  7
     5  4  =  23
     7  6  =  47
     9  8  =  79
    10  9 =  ?

A: Multiply the two number and add odd numbers in ascending order

     3 x 2 + 1 = 7, 5 x 4 + 3 = 23, 7 x 6 + 5 = 47, 9 x 8 + 7 = 79 and 10 x 9 + 9 = 99

Q: IF, 2 = 6
          3 = 12
          4 = 20
          5 = 30
          6 = 42
THEN,
          9 = ?

A: 9 X 10 = 90 OR 9 X 9 + 9 = 90
