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 = a2
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
⇒ a2 = 9604
⇒ a = 98
∴ The total number of chairs in each row is 98.
