5 kg of adulterated rice has 2% stones in it and the rest is rice. Half of the stone
content was removed. Now the percentage of stone content in it is
1. 0.99%
2. 1%
3. 1.1%
4. 1.01%

• 1.01 percent initially 2%stones of 5000gms of rice is 100 grams later half of stones removed that is 50 grams removed so percentage of stones is (50/4950)x100=1.01%

• 2% of 5=0.1
  Half of the stone has been remove so stone becomes 0.1/2=0.05
  Total wt. becomes 5-0.05=4.95
  % of stone=0.05*100/4.95=1.01%
  Ans:d.1.01%
