Percentage: Level 1
1.
What is 0.5% of 200?
Solution (C):
\( 0.5\% = \frac{0.5}{100} = 0.005 \).
\( 0.005 \times 200 = 1 \).
2.
If 30% of a number is 60, what is the number?
Solution (B):
\( 0.30x = 60 \implies x = \frac{60}{0.3} = 200 \).
3.
A shirt priced at $50 is sold for $40. What is the percent discount?
Solution (D):
Discount amount = \( 50 – 40 = 10 \).
Percent = \( \frac{10}{50} \times 100\% = 20\% \).
4.
If you increase 80 by 25%, the result is:
Solution (A):
\( 25\% \text{ of } 80 = 20 \).
New value = \( 80 + 20 = 100 \).
5.
In a class of 50 students, 40% are boys. How many girls are there?
Solution (E):
If 40% are boys, then \( 100\% – 40\% = 60\% \) are girls.
\( 60\% \text{ of } 50 = 0.6 \times 50 = 30 \).
6.
Which of the following is equal to 3.5%?
Solution (B):
To convert percent to decimal, divide by 100.
\( 3.5 \div 100 = 0.035 \).
7.
What is the fraction equivalent of 125%?
Solution (C):
\( 125\% = \frac{125}{100} = \frac{5}{4} \).
8.
A 30% discount on a $200 item reduces the price by how much?
Solution (A):
Amount reduced = \( 30\% \text{ of } 200 = 0.3 \times 200 = 60 \).
9.
If \(x = 25\) and \(y = 100\), what percent of \(y\) is \(x\)?
Solution (C):
\( \frac{x}{y} \times 100 = \frac{25}{100} \times 100 = 25\% \).
10.
What is the result when 50% of 10 is added to 10% of 50?
Solution (D):
\( 50\% \text{ of } 10 = 5 \).
\( 10\% \text{ of } 50 = 5 \).
Sum = \( 5 + 5 = 10 \).
