A shopkeeper professes to sell his goods at cost price but uses a weight of 800 gm instead of kilogram

Let c.p. of 1000gm =100
then c.p. of 800 gm =80
but s.p. of 800 gm =100(as weight shows800 gm instead of 1000 gm)
so profit = s.p-c.p =100-80 = 20% (ans)
ans:a) 20%

Let 1 kg cost = 100
800gm cost = 80
800 gm selling price =100

profit= 100-80=20
profit % = (20/80)*100 = 25%

suppose the cost price of good is 100 per kg then shopkeeper is selling it at 100 per 800g ...which is 125 per kg. so the profit is 25%

Ans is 25%.
If we let CP for 1000 gm as rs. x
then according to question, SP for 800 gm will be rs. x
new SP for 1000 gm=rs. 5x/4
profit for 1 kg or 1000 gm=SP-CP=(5x/4)-x = Rs. x/4
profit%=profit*100/CP=(x/4)*100/x=25%

Formula Method :
(m - n)/n * 100

m = 1000
n = 800
= (1000 - 800)/800 * 100
= 200/800 * 100
= 25% (Option C)
