Well Its too easy directly using Charles law and Boyle's law. but firstly we have to convert temp into kelvin scale ie. 20° becomes 293.15k.. and then formulating and solving we get P1×V1÷T1=P2×V2÷T2 = 760×1000/293.15=750×1400/T2 =1050000/2592.5=T2= 405.01 .. Now Since we want it in Degree scale.. just minus it from 405.01-273.15= 131.86° and thats It..
