Solution in JAVA (judge verdict: Accepted)

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.math.BigDecimal;

class Main {


	public static void main(String[] args) {

		// ストリームを作成する
		BufferedReader reader = new BufferedReader(new InputStreamReader(
				System.in));

		int week = readNumber(reader);
		BigDecimal debt = BigDecimal.valueOf(100000);
		for (int i = 0; i < week; i++) {
			// 5%の利子を追加し、1000円未満は切り捨て
			debt = debt.multiply(BigDecimal.valueOf(1.05)).setScale(-3, BigDecimal.ROUND_UP);
		}
		System.out.println(debt.toPlainString());

	}
