Question

find the cost price of an article which was sold at 10,000 rupees there by losing 20% ..

Answer 1

Loss = 20%

Selling Price = 100 - 20 = 80%

Selling Price = 80%

Selling Price = Rs 10,000

80% = Rs 10,000

1% = 10,000 ÷ 80 = Rs 125

1% = Rs 125

100% = 125 x 100 = Rs 12500

Answer: The cost price is  Rs 12500

Answer 2

AN ARTICLE WAS SOLD AT 10,000 RS BY LOSING 20%

SELLING PRICE IS 80% OF COST PRICE

SO

COST PRICE = $\frac{100}{80}$ × 10,000 = 12,500 RS

HENCE

COST PRICE = 12,500 RS
