Question

Three percent of $4,200$ is equal to $6$ percent of what number?

• A. $8,400$
• B. $2,100$
• C. $1,260$
• D. $252$
• E. $126$

Answer 1

The correct option is B $2,100$

Three percent of $4200$ is $\frac{3}{100}\times 4200=126$, which is equal to six percent of some number.

Let the number be $x$.

Therefore we get $126=\frac{6}{100}\times x$.

Which implies $x=2100$.
