Problem:
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 items

After-tax price with 5% VAT

After-tax price with 8% VAT

20, 80

21 + 84 = 105

21 + 86 = 107

2, 99

2 + 103 = 105

2 + 106 = 108

13, 88

13 + 92 = 105

14 + 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%.

is given for each dataset of the sample input.
