Let, the second successive discount be $x \%$

Now, according to the question,

$3200\left(1-\frac{10}{100}ight)\left(1-\frac{x}{100}ight)=2448$

$\Rightarrow \quad 3200 	imes \frac{90}{100} 	imes\left(1-\frac{x}{100}ight)=2448$

$\Rightarrow 1-\frac{x}{100}=\frac{2448}{2880}$

$\Rightarrow \frac{x}{100}=1-\frac{2448}{2880}=\frac{432}{2880}=\frac{3}{20}$

$	herefore \quad x=\frac{300}{20}=15 \%$

The rate of second discount is $15 \%$
