The charge on a capacitor increases by 23 µC when the voltage across it increases from 80 V to 121 V. What is the capacitance of the capacitor?

The formula for voltage vs charge on a capacitor is
C*∆V = ∆Q
Therefore C = ∆Q/∆V

The charge held by a capacitor is proportional to the voltage applied. The difference in the amount of charge on the capacitor divided by the difference in voltage should be the capacitance.

did the capacitor have a charge before induced current.

your question only makes reference to voltage, and excludes inductance.
