50% increase in prressure

Let
$P_1->"Initial presure"$

$V_1->"Initial volume"$

$T_1->"Initial temperature"$

$P_2->"Final presure"$

$V_2->"Final Volume"$

$T_2->"Final temperature"$

By the given condition

$V_2/V_1=2 " " T_2/T_1=3$

By gas law equation

$(P_2V_2)/T_2=(P_1V_1)/T_1$

$=>(P_2xx2V_1)/(3T_1)=(P_1V_1)/T_1$

$=>P_2/P_1=3/2$

$(P_2-P_1)/P_1=3/2-1=1/2xx100%=50%$

So there 50% increase in prressure
