```							At constant temp. that is at isothermal.P1V1 = constant.so we could say here that Pressure would be inversely proprtional to the volume from here Boyl’s law.Let PV = k …..........(1)after dcreasing pressure by 10% that is V net = V – 0.1V = 0.9 V this is remaining Volume.Now,P’ * 0.9V = k...............(2)divid ethe both eqn.P/0.9P’ =  1orP’ = P/0.9 =  > 10P/9 = 1.111P% increase in Pressure = > (1.11P – P)/P => 0.11P/P = > 0.11= 11%
