Tax Rate Changed
    VAT (value-added tax) is a tax imposed at a certain rate proportional to the sale price.
  
    Our store uses the following rules to calculate the after-tax prices.
    
	When the VAT rate is x%,
	for an item with the before-tax price of p yen,
	its after-tax price of the item is p (100+x) / 100 yen, fractions rounded off.
      
	The total after-tax price of multiple items paid at once is
	the sum of after-tax prices of the items.
      
    The VAT rate is changed quite often.
    Our accountant has become aware that
    "different pairs of items that had the same total after-tax price
    may have different total after-tax prices after VAT rate changes."
    For example, when the VAT rate rises from 5% to 8%,
    a pair of items that had the total after-tax prices of 105 yen before
    can now have after-tax prices either of 107, 108, or 109 yen, as shown in the table below.
  
Before-tax prices of two itemsAfter-tax price with 5% VATAfter-tax price with 8% VAT
20, 8021 + 84 = 10521 + 86 = 107
2, 992 + 103 = 1052 + 106 = 108
13, 8813 + 92 = 10514 + 95 = 109
    Our accountant is examining effects of VAT-rate changes on after-tax prices.
    You are asked to write a program that calculates the possible maximum
    total after-tax price of two items with the new VAT rate,
    knowing their total after-tax price before the VAT rate change.
  
Input
    The input consists of multiple datasets.
    Each dataset is in one line,
    which consists of three integers x, y, and s separated by a space.
    x is the VAT rate in percent before the VAT-rate change,
    y is the VAT rate in percent after the VAT-rate change,
    and s is the sum of after-tax prices of two items before the VAT-rate change.
    For these integers, 0 < x < 100, 0 < y < 100,
    10 < s < 1000, and x ≠ y hold.
    For before-tax prices of items, all possibilities of 1 yen through s-1 yen should be considered.
  
    The end of the input is specified by three zeros separated by a space.
  
Output
    For each dataset,
    output in a line the possible maximum total after-tax price when the VAT rate is changed to y%.

Hints
    In the following table,
    an instance of a before-tax price pair that has the maximum after-tax price after the VAT-rate change
    is given for each dataset of the sample input.
