Question

A tea set was bought for rate 528 after getting a discount of 12percent on its marked price find the marked price of the tea set

Answer 1

let marked price be x
discount 12 percent on its marked price
so cost price be
$x - (x \times \frac{12}{100} ) = x - \frac{3x}{25} = \frac{22x}{25}$
now
$\frac{22x}{25} = 528 \\ or \: x = \frac{528 \times 25}{22} = 600$
so the marked price be 600
