  • A
    $100$
  • B
    $200$
  • C
    $300$
  • ✓
    $400$
✓

Answer

Correct option: D.
$400$

$25\%\ \text{of x}=100$
$\Rightarrow\frac{25}{100}\times\text{x}=100$
$\Rightarrow\frac{\text{x}}{4}=100$
$\Rightarrow\frac{4\times\text{x}}{4}=4\times100$
$\Rightarrow\text{x}=400$
Hence, the correct option is $(d).$
