multiply a number by percentages and round so that they add upto the total %

I want to multiply a number say, 1551 by 5%, 6%, 7%, 8% and 9% and round each result to 0 decimal places. Then the sum of these results (544)should be equal to 35% of 1551 rounded to 0 decimal places (543). How do I create an if function for rounding so that the sum equals 543.
