2-variations

The pressure of gas under constant heat condition is found to vary inversely with the volume raised to the power of γ, where γ is the ratio of specific heat of the gas under constant pressure to constant volume, and is found to be 1.14. A student observes that a certain gas occupies a volume of 22.4 litres under 3 kg /cm2 pressure. What will be the pressure of gas if the same quantity of gas is reduced to 11.2 litres?
