Question

A book was marked at a discount of 23%. If it was sold for ₹231, then what was the marked price?

• A. ₹300
• B. ₹250
• C. ₹271
• D. ₹321

Answer 1

The correct option is A ₹300

Let the M.P = ₹ x
Discount allowed = 23%
$\Rightarrow$ S.P = x - 23% of x
and S.P = ₹231
So, x - 23% of x = 231
$\Rightarrow$ x - $\frac{23}{100}\times$ x = 231

$\Rightarrow$ 77x = 231 $\times$ 100

$\Rightarrow$ x = $\frac{23100}{77}$

$\Rightarrow$ x = 300

So, the marked price is ₹300
