Question

a shopkeeper buys an item for 40% off the marked price. by what par can't should be increased the marked price so that even after allowing a discount of 20%, he makes a profit of 40%​

Answer 1

Answer:

20%

Step-by-step explanation:

let the marked price when he bought be 100

100-40 (when he bought)

10+60 ( his gain)

100+20 ( discount)

= 120

So, 100% was increased to 120%

120-100

20%
