The marked price of a laptop is ₹65,000. The laptop is sold at a discount of 20%.
Selling price of a laptop = ₹65,000 of (100-20)%
= ₹65,000 of 80%
= $$65,000\times\frac{80}{100}$$
= 52,000
If a profit of 30% is made through the sale, then the Cost price of the laptop = $$\frac{52,000}{\left(100+30\right)}\times100$$
= $$\frac{52,000}{130}\times100$$
= $$400\times100$$
= ₹40,000
