Question

A shopkeeper allows a discount of 15% on the Marked price how much above the cost price must he marks his goods to make a profit of 19%

Answer 1

Hello guys Namaste,

$Solve = >$

$Marked \: Price(100 - discount\%) = Cost \: Price(100 + gain\%)$

$MP \: (100 - 15) = CP(100 + 19)$

$MP(85) = CP(119)$

$MP = \frac{119}{85}$

$MP = 1.4 \: CP$

$= > \: (1 + 0.4) \: CP$

MP is 0.4% more than CP.

So, CP must be 40% .
