A $\displaystyle 5 \mu \mathrm{~F}$ capacitor is charged fully by a $\displaystyle 220$ V supply. It is then disconnected from the supply and is connected in series to another uncharged $\displaystyle 2.5 \mu \mathrm{~F}$ capacitor. If the energy change during the charge redistribution is $\displaystyle \frac{\mathrm{X}}{100} \mathrm{~J}$ then value of X to the nearest integer is \_\_\_\_.
