Given that diameter of a paint can is 6.2483.
And we are asked to find width of four paint cans on a shelf.
Since we can only place paint cans adjacent to each other on a shelf, Total width will be addition of diameters of four paint cans.
Hence width = 6.2483+6.2483+6.2483+6.2483
= 24.9932 ≈ 24.99 inches( rounded off to nearest hundredth of an inch)
Hence correct option is 'A'.
