Answer 1

Correct Answer - Option 3 : 50

Given :

A shopkeeper claims to sell items at no profit no loss . 

If he underweights items 800 grams in place of one kg and  adds 20% impurities,

then his profit % = ?

Calculation :

Let assume  that the cost of 1 kg is Rs. 1 

If the seller bought sugar at Rs. 800,

He would sell at this at Rs. 1000

Since there is 20% impurities also in sugar whose CP is = Rs. 800 is sold at

⇒ 1000 + 20% of 1000 = Rs. 1200

Then , profit = 1200 - 800 = 400

Profit % = (400/800) × 100 = 50%

⇒ Profit percentage (%) = 50%

∴ The profit percentage is 50%
