Hi,

I think the answer is C. At most you can place 96 glasses on the table.

Circumference is 4 * 3.14. Therefore the diameter of each glass is

3.14 * d= 3.14 * 4 i.e. 4. Now with a diameter of 4, how many glasses can be put along the length of the table? It will be 48/4=12.

Similarly along the width 32/4=8. Therfore, total glasses that can be placed are 12*8=96.

HTH,

ash
