A charged capacitor when connected to uncharged one

[r0ss]

Homework Statement

A capacitor of capacitance 10 uF is raised to a potential difference of 150V. After disconnecting from the battery, it is connected to a capacitor of capacitance 5 uF. Find the energy of the system.

Homework Equations

Energy supposed to be equal in the first case and second case right? But the solution showed that the energy is decreased as the capacitor is connected with uncharged one. Which one is right?

The Attempt at a Solution

Solution for first assumption: 0.1125 J.
Solution for the second: 0.075 J.

There will be an energy loss, which is dissipated in the non-zero resistance of the connecting wires. If you search on Google saying "Energy losses on connecting two capacitors", you will get tons of results, like this one.
