[tex]\frac{1}{4}\times \frac{3}{5}[/tex]
In Option 'C' ,
Length of a poster is given by
[tex]\frac{1}{4}[/tex]
Width of a poster is given by
[tex]\frac{3}{5}[/tex]
So, Area of poster is given by
[tex]Length\times breadth\\\\=\frac{1}{4}\times \frac{3}{5}[/tex]
In option 'B', part of dolls are within the original box is given by
[tex]\frac{3}{5}[/tex]
Part of dolls who has charity is given by
