A person has with him a certain number of weighing stones of 100gm, 500gm and 1 kg in the ratio of 3:5:1. If a maximum of 5 kg can be measured using weighing stones of 500gm alone, then what is the number of 100 gm stones he has?

• Ans 6
  
  Number of 500gm stones = 5kg/500gm = 10
  
  Ratio = 3:5:1 or 6:10:2
  
  Thus no. of 100gm stones = 6

• 5 kg can be weight by 500 gm alone that mean no of 500gm is === 5000/500 ==10 ;
  suppose total no of weights is x; so 5/9*x == 10 and x=18; then total no of 100gm == 3/9 * 18 == 6;
