The correct option is C 125 %
Formula of the area of a square is (side)2
The area of the larger table = 152=225 sq. ins.
The area of the larger table = 102=100 sq. ins.
To find the percentage, the larger table is large by the smaller table, we get the equation as
(225−100)100=125100
That is 125%
Hence, the correct answer is the option C, 125%.
