The problem statement tells you the ratio of force to area is the same for all pairs. This means, for example, ...
3750/250 = 5625/x = y/420
Simplifying, this becomes the two equations ...
15 = 5625/x ⇒ x = 5625/15 = 375
15 = y/420 ⇒ y = 420·15 = 6300
The values of x and y are (x, y) = (375, 6300). . . . . matches choice C
