.If selling an article for ₹820 causes 10% loss on the selling price,then find itsb costprice.​

Answer»

Solution!!

The concept of profit and LOSS has to be used here. The selling price (SP) and loss PERCENTAGE is given. We have to find the cost price (CP).

Loss% = 10

Selling price (SP) = Rs 820

SP = CP × (100 - Loss%)/100

820 = CP × (100 - 10)/100

820 × 100 = CP × 90

82000 ÷ 90 = CP

CP ≈ Rs 911.11

Hence, the cost price is Rs 911.11

More information:-

If SP>CP, then it is profit.

If CP>SP, then it is loss.

Profit = SP - CP

Loss = CP - SP

Profit% = (Profit/CP) × 100

Loss% = (Loss/CP) × 100

CP → Cost Price

SP → Selling Price
