Dot against inductors determine the phase difference of source and load. Dots in opposite directions means that load is at 180 degrees out of phase with source.

Primary side voltage=40 and the turns ratio is 3:1
So secondary side voltage is 40/3=13.33v rms in out of phase.
So secondary side voltage is 40/3=13.33v rms in out of phase.

Vs=Ns/Np*Vp
Vs=1/3*40
Vs=13.33v
Vs=1/3*40
Vs=13.33v

Why the phase will be different?

The phase is diferent because dots are on opposite sides of the coils.

Secondry coil voltage=40v.
Turn ratia=3:1
acording formula,
Np/Ns=Vp/Vs
3/1 =40/Vs
Vs=13.33v
Turn ratia=3:1
acording formula,
Np/Ns=Vp/Vs
3/1 =40/Vs
Vs=13.33v

How can we say whether it is in phase or out of phase?

The dots represents same sign. Those dots are opposite sides so it is out phase.

Please can anyone say that what is the effect of 'in phase' and 'out of phase' ?

V1/V2= N1/N2.
40/V2 = 3/1.
V2 = 40/3.
V2 = 13.33 V OUT OF PHASE DUE TO OPPOSITE POLARITY.
40/V2 = 3/1.
V2 = 40/3.
V2 = 13.33 V OUT OF PHASE DUE TO OPPOSITE POLARITY.
