Question

a man bought 10 lampshades . he sold them at rs 75 each , thereby making a profit of rs 70 in total . what was the cp of one lampshade

Answer 1

Let the CP of each lampshade=Rs.x

CP of lampshade=Rs.10x

SP of lampshade=10x75=Rs.750

Profit=SP-CP (since it is given in the question)

70=750-10x

70-750=-10x

-680=-10x

x=680/10

x=68

CP of lampshade=Rs.10x=Rs.10(68)=Rs.680
