According to the reaction:
by set ICE table:
                   CO(g) + H2O(g) ↔ CO2(g) + H2(g)
initial         1320      1760              0              0
change        -X         -X                +X             +X
initial      (1320-X)    (1760-X)        X               X

when Kp = (pressure products)/ (pressure reactants )
 Kp = P(H2)* P(CO2) /P(CO) * P(H2O)
by substitution:
0.0611 = (X * X) / (1320-X) * (1760-X)
0.0611 = X^2 / (X^2-3080X + 2323200)

∴X = 301 torr 
∴P(CO2) = X = 301 torr
