Answer:
Cp is 600
Step-by-step explanation:
let the initial CP is 100x
A shopkeeper sells his goods at 20x profit.
Profit=SP-CP
20 x=SP-100x
SP=120x
had he purchased it for 10% less and sold it rs 18 less than he would have gained 30%.
if he purchased 10% of x less
CP=100x-10x
CP=90 of x
SP=120 of x-18
Profit%=((SP-CP)/CP)*100
30 =((120 x-18-90 x)/90x)*100
30=30x-18/90x*100
27x=30x-18
3x=18
x=6
CP=100*6
CP=600
