Let us assume that the volume of each marble be v ml. Let the gas behave as an ideal gas. Assume that the compression is done as an isothermal process.

P1 = 2 atm

Initial volume of the gas = V1 = 1000 - 10 v   ml

P2 = 4 atm

V2 = 725 - 10 v   ml

Using Gas equation:    P1 V1 = P2 V2

=>  2 (100 - 10v) = 4 (725 - 10v)

=> 20 v = 900

=> v = 45 ml
