Question

By how much percent above the cost price should a shopkeeper marks his goods so that he may gain 10% even after allowing a discount of 12% on the marked price

Answer 1

Step-by-step explanation:

let the cost price be 100 rupees

gain= 10% ,thenselling price = 110

Let marked price be x

then discount =12% of x

( x ×12/100) = ( 3x /25 )

selling price =( mp) -( discount)

(x-3x/25)= 22x/ 25

now we put the sp = 22x/25= 110

x= 110×25/22

x = 125 ans

If you want to change in percent the you change it
