The number of girls appearing for an admission test is twice the number of boys. If 30% of the girls and 45% of the boys get admission, the percentage of candidates who do not get admission is

Correct Option: D

Let the number of boys appearing for the admission test be $B=100$.

Since the number of girls is twice the number of boys, the number of girls is:
$G=2\times 100=200$

The total number of candidates is:
$\text{Total}=100+200=300$

Now, calculate the number of candidates who get admission:

• Number of girls getting admission = $30\%\text{of}200=60$
• Number of boys getting admission = $45\%\text{of}100=45$

Total candidates who get admission = $60+45=105$.

The number of candidates who do not get admission is:
$300-105=195$

The percentage of candidates who do not get admission is:
$\frac{195}{300}\times 100\%=65\%$
