Answer 1

Marked Price = Rs 8000 (Given)

Find the price after discount:

Discount = 20%

Discount = 0.2 x 8000

Discount= Rs 1600

Price after discount = 8000 - 1600 = Rs 6400

Find the cost price:

Profit = 25%

Selling Price = Cost Price + Profit

Selling Price = 100 + 25 = 125%

Selling Price = Rs 6400

125% = Rs 6400

1% = 6400 ÷ 125

1% = Rs 51.20

1% = Rs 51.20

100% = 51.20 x 100 = Rs 5120

Answer: The cost price is Rs 5120
