A. 40
B. 38
C. 35
D. 45
Answer & Solution
Answer: The correct answer is 35.
Solution:
By using Substitution we form an equation
What\ \ \ is\ \ \ 10\%\ \ \ of\ \ \ 350
\downarrow\ \ \ \ \ \ \ \ \ \downarrow\ \ \ \ \ \ \downarrow\ \ \ \ \ \ \ \ \downarrow\ \ \ \ \ \ \downarrow\
x\ \ \ \ \ \ \ =\ \ \ \frac{10}{100}\ \ \ \ \times\ \ \ 350
x\ =\frac{10}{100}\times350
x\ =\ \frac{10\ \times350}{100}
x\ =\ \frac{3500}{100}
x\ =\ 35
Hence, 35 is 10 percent of 350.
