Q.1 Easy Mathematics

What is 15% of 240?

A 36

B 40

C 45

D 48

Correct Answer: A. 36

Explanation:

To find a percentage of a number, multiply the number by the percentage expressed as a decimal: \(15\% \text{ of } 240 = 0.15 \times 240\).

Step 1: Convert percentage to decimal

Convert 15% to its decimal form:

15\% = \frac{15}{100} = 0.15

Step 2: Multiply by the base number

0.15 \times 240 = 36

Alternatively, using fractions:

\frac{15}{100} \times 240 = \frac{15 \times 240}{100} = \frac{3600}{100} = 36
