Correct Answer - Option 4 : 98

**Given:**

Total chairs needed = 9610

The chairs being left out = 6

**Concept used:**

The area of square = Area occupied by the total chairs

The sides of the square = Number of a chair in each row

**Formula used:**

Area of square = a^{2}

a = side of the square

**Calculation:**

According to the question,

The total chair available = 9610 - 6

⇒ The total chair available = 9604

Now,

The area of square = Area occupied by the total chairs

⇒ a^{2} = 9604

⇒ a = 98

**∴ The total number of chairs in each row is 98.**
