Well, I had expected a solution in this one cause you gave that tiny filthy little box on each and every question.

Ans 10:

Class : Class 10
(First Column) (3 X 5 X 4) – 36 = 24 = 2 to power 3 2 to power 4Note: Exponential power 3 = from first column first cell, Exponential power 4 = from first column third cell(Second Column) (Ans 4 X 4 X 4) – 32 = 32 = 2 to power 4 2 to power 4Note: Exponential power 4 = from second column first cell, Exponential power 4 = from second column third cell(Third Column) (5 X 7 X 6) – 114 = 96 = 2 to power 5 2 to power 4Note: Exponential power 5 = from third column first cell, Exponential power 4 = from third column third cell

Ans 11:

Class : Class 9
Solution?

Ans 12:

Class : Class 10
(First Column) (3 X 5 X 4) minus 36 = 24 = 2 to power 3 2 to power 4Note: Exponential power 3 = from first column first cell, Exponential power 4 = from first column third cell(Second Column) (Ans 4 X 4 X 4) minus 32 = 32 = 2 to power 4 2 to power 4Note: Exponential power 4 = from second column first cell, Exponential power 4 = from second column third cell(Third Column) (5 X 7 X 6) minus 114 = 96 = 2 to power 5 2 to power 4Note: Exponential power 5 = from third column first cell, Exponential power 4 = from third column third cell
