Question

What percentage of 300 is 45?

• A. 15
• B. 16
• C. 17
• D. 18

Answer 1

The correct option is A 15

$\text{Let 45 be}x\text{pecentage of 300}$
So,
$\to x\%of300=45$

$\text{1\% is 1 part out of 100},\to 1\%=\frac{1}{100}$

$\text{So,}x\%\text{is}x\text{part out of 100,}\to x\%=\frac{x}{100}$

$\therefore \to x\%of300=45$

$\to \frac{x}{100}\times 300=45$

$\to x\times 3=45$

$\to x=\frac{45}{3}=15$
Hence, 15% of 300 is 45.
