Question

The cost of a pair of shoes is Rs 1600 after a discount of 40%. find the marked price​

Answer 1

let marked price be Rs. x

$cost \: price \: = x - 40\%x \\ \\ = > 1600 = x - \frac{40x}{100} \\ \\ = > 1600 = x - \frac{2x}{5} \\ \\ = > 1600 = \frac{3x}{5} \\ \\ = > x = \frac{1600 \times 5}{3} \\ \\ = > x = 2666.66$

marked price = Rs. 2666.66
