Solution

The correct option is B 25
Side of tin sheet = 1 m = 100 c.m.
Area $= (100)^{2} = 10000 c . m^{2}$
Area of tin sheet to be cut $= (20)^{2} = 400 c . m^{2}$
Let number of sheets = k
$\Rightarrow (400)$ $k = 10000$
$\Rightarrow k = \frac{10000}{400} = 25$
$\Rightarrow 25$ sheets can be made
