Correct Answer: (4)
Solution: (4)
Let the number be $x$.
$\therefore 26^{2}-\frac{x \times 53}{100}=358$
$\Rightarrow 676-\frac{x \times 53}{100}=358$
$\Rightarrow \frac{x \times 53}{100}=676-358=318$
$\Rightarrow x=\frac{318 \times 100}{53}=600$
$\therefore 600 \times \frac{23}{100} \times \frac{3}{4}=103.5$
