• 22%...Since Alex collected 54 coins, we've 46 remaining. Questions says Calvin collected 2 more than double collected by Drona. What we can deduct from this statement?
  
  Since everybody collected not less than 10 coins, the only option where one can collect more than double of the other and that total to 46 is when the person has collected least number possible.
  
  That means Drona collected 10, Calvin collected (2 * 10 + 2 = 22) and Bond collected 14. So % of coins collected by Calvin is 22%

• assume the total amount is 100.alex collects 54,the remaining coins is 46,lets assume dora collects x coins and the calvin collects 2x+2.
  then x+2x+2=46
  3x=44
  x=44/3
  calvin collects 2*44/3 + 2 which approximately 31%..
  so the option is (b)
