Question

A shopkeeper sells his goods at a profit of 30% and uses weight 900k
G for 1 kg weight.whay is actual gain percentage of shopkeeper

Answer 1

let cp of 1 kg goods = 1000 rupees

then cp of 900grams = 900 rupees

profit = 30%

sp = cp(1+g%)

=900(1+30%)

= 900×1.3 = 1170 rupees

actual cp= 1000 rupees

sp =1170

actual gain% = sp-cp / cp ×100

= 1170 - 1000/1000 ×100

=170/10 = 17%
