Question

by selling an article for rupees 18 A shopkeeper loses 10% of its cost price at what price should he sell this article in order to make 10% profit on its cost price

Answer 1

here Sp = 18
loss% = 10
cp= 100/(100-10) × 18
cp = 100/90 × 18
= 20

now to make profit of 10% sp should be

sp = (100+10)/100 ×cp
sp =110/100 ×20
sp = 22
so he should sell it at a price of 22

HOPE IT HELPS......THANKYOU
