I = Prt\qquad 
\begin{cases}
I=\textit{interest earned}\to &\$2\\
P=\textit{original amount}\to& \$25\\
r=rate \\
t=years\to &\frac{1}{2}
\end{cases}$

katrin2010 [14]

Let, total number of T-shirts are x.

Number of blue T-shirts = (2/3)x = 2x/3 .

Number of blue shirts on sale = (3/5)(2x/3) = 2x/5 .

Number of medium sized blue shirts on sale = (1/5)(2x/5) = 2x/25 .

Fraction of the shop's T-shirts are blue T-shirts that are on sale and are size medium = $\dfrac{2x/25}{x}$ = 2/25 . ( Number of medium sized blue shirts on sale divided by total number of T-shirts )
