Question

Anad paid Rs30 as sales tax on a bottle of mineral water with marked price as Rs 400. Calculate the rate of sales tax.

• A. 15%
• B. 12.5%
• C. 6%
• D. 7.5%

Answer 1

The correct option is D 7.5%

Marked price=$Rs400$

Sales tax=$Rs30$

Let the rate of sales tax be $x$

Therefore,

$\Rightarrow x\%of400=30$

$\Rightarrow \frac{x}{100}\times 400=30$

$\Rightarrow 4x=30$

$\Rightarrow x=\frac{30}{4}$

$\Rightarrow x=7.5\%$
