Question

If 12% of A is equal to 15% of B, then 16% of A is equal to what percent of B?

• A. 18%
• B. 19%
• C. 20%
• D. 21%

Answer 1

Answer:

C. 20%

If 12% of A is equal to 15% of B,

$\frac{12}{100}\times{A} = \frac{15}{100}\times{B}$

$A = \frac{15}{12}\times{B}$

16% of A = x% of B

$\frac{16}{100}\times{A} = \frac{x}{100}\times{B}$

16A = xB

$16\times{\frac{15}{12}}\times{B} = xB$

$x = 16\times{\frac{15}{12}}$ = 20%
