Ideal Gas Equation : pv = nRT
Here , n,R and T are constant
So , p is inversely proportional to v
p(i)/p(f) = v(f) / v(i)
p(f) = 250/200 × 0.98 = 1.225 bar
Additional Pressure : 1.225 - 0.98 = 0.245 bar

Let p be the additional pressure...
then,
pV/T = constant
pV = constant
0.98 × 250 = (0.98+p) × 200
200×p = 0.98 × 50
p = 49/200
p = 0.245 bars
