Question

A shirt was sold for $ 425 after allowing 15 %​

Answer 1

Eh.... 15% discount right?

Cost price = x (say)

According to the problem,

$x - \frac{15}{100} \times x = 425 \\ = x - \frac{3x}{20} = 425 \\ = \frac{17x}{20} = 425 \\ = \frac{x}{20} = 25 \\ = x = 500$

Therefore, cost price = $500
