Correct Answer: 21.43%

Solution : $\frac{2}{5}$ × marked price = $\frac{4}{7}$ × cost price
Marked price = $\frac{10}{7}$ × cost price
Discount = 15% of marked price
= $\frac{15}{100}×\frac{10}{7}$ × cost price
Selling price = marked price – discount

Correct Answer: 2555

Solution : $12.50\ ÷ \ 0.005 + 25\ ÷\ 0.5 + 5 = x$

$⇒x=\frac{1250×1000}{5×100}+\frac{250}{5}+ 5$
$⇒x=2500+50+5$
$\therefore x=2555$
Hence, the correct answer is 2555.
