at a constant temperature   P is infersely  proportionsl  to   1/V

PV=comstant

at same temperature apply P1V1 = P2V2

thus u will get P as 1.15 bar

P1V1=P2V2
.92*.6= .12*P2

P2= 4.6 bar :answer

Hi Tejas,

V1=0.6 lit

V2=V1-V1*20/100

    = V1(1-20/100)=V1(80/100)

P1=0.92 bar

Boyle's law: P1*V1=P2*V2

                 0.92*V1=P2*V1*0.8

                  P2=0.92/0.8=1.15 bar
