how much should he sell this LED to gain 30%?
2. A shopkeeper bought an article for 2000 and sold for
2500. Find his gain% or loss%.​

Answer 1

Step-by-step explanation:

1. Selling price of LED =18000

loses% =10%

cost price of LED =20000

S.P. =C.P./100×(100-loss%)

18000 =C.P./100×(100-10)

18000 = C.P./100×90

18000×100 =90×C.P.

1800000/90 =C.P.

2000 =c.p.

cost price =20000

profit =30%

selling price =2000/100(100+30)

=20000/100×130

=26000 ans
