Answer

48 Volts

Explanation

The question can be solve using the turn rule of a transformer that states;

Np/Ns = Vp/Vs

Where Np ⇒ number of turns in the primary coil.

Ns ⇒number of turns in the seconndary coil

Vp ⇒ primary voltage

Vs ⇒secondary voltage

Np/Ns = Vp/Vs

10/4 = 120/Vp

Vp = (120 * 4) / 10

= 480/10

= 48 Volts
