Question

If 100% of a number is 15, what is 50% of the same?

• A. 7
• B. 7.5
• C. 8
• D. 8.5

Answer 1

The correct option is B

7.5

Let the number be x.
100% of number is 15 means,
$\frac{100}{100}\times x=15$
$x=15$
Therefore the number is 15.
Now 50% of this number would be,
$\frac{50}{100}\times 15$
$=7.5$
