A. 25%

B. 30%

C. 35%

D. 75%

### Answer & Solution

**Answer:**The correct answer is 75%.

**Solution:**

By using Substitution we form an equation

What\ \ \ \ \ Percent\ \ \ \ \ \ of\ \ \ \ \ \ 24\ \ \ \ \ \ \ is\ \ \ \ \ \ 18

\downarrow\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \downarrow\ \ \ \ \ \ \ \ \ \ \ \ \ \downarrow\ \ \ \ \ \ \ \ \downarrow\ \ \ \ \ \ \ \ \downarrow\ \ \ \ \ \ \ \ \downarrow\

x\ \ \ \ \ \ \ \ \ \ \ \ \ \frac{1}{100}\ \ \ \ \ \ \ \ \ \ \ \times\ \ \ \ \ \ 24\ \ \ \ \ \ =\ \ \ \ \ \ 18

⇒\ \frac{x}{100}\times24\ =\ 18

⇒\ \ x\ \times24\ =\ 18\ \times100

⇒\ \ x\ =\frac{18\ \times100}{24}

x\ =\ 75\%

**Hence, 75% of 24 is 18.**
