Apparent Power = 125+ 150 =275/1.41=195.2w

The above solution is wrong
The correct one is sqrt( 125^2 + 150^2 ) = 195.2
The correct one is sqrt( 125^2 + 150^2 ) = 195.2

Units should be in VA. i.e. 195.2VA.
True power - Watts.
Reactive power - VARS.
Apparent power - VA/KVA.
True power - Watts.
Reactive power - VARS.
Apparent power - VA/KVA.

kva = sqrt(true power)*sqrt(reactive power).

kva = square root of kw^2+kvar^2.

@ALL.
(app)^2=(tru p)^2+(react p)^2.
so, app p=sqrt of tru^2+react^2.
(app)^2=(tru p)^2+(react p)^2.
so, app p=sqrt of tru^2+react^2.

The answer should be 195.25 VA.
