It would be 100. Because let's say you had to round 25 to the nearest 10 it would be 30 because everything ending with 5 (example: 5 to nearest 10 would go to 10 65 to the nearest ten would go to 70) but anything lower then 5 goes to the lower number.
'y' is NOT the number of chairs in each row and column. It's the TOTAL number of
chairs, so it's the product of (chairs in each row) times (chairs in each column).
The problem says that those numbers are equal. So we would expect the TOTAL
to be a perfect square, and the number in each row and each column to be the
square root of the total. Since the total is 81, the number in each row and column
could be either +9 or -9 . Both answers are mathematically correct, but -9
doesn't make sense in the real world. So we know that +9 is the real answer.
