Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

when base voltage is zero .. there is no flow of current to the transistor. so, Vbe is less than 0.7. then the transistor will be in cutoff region and acts as open switch between collector and emitter terminals. so the output voltage =Vcc. So, here the answer is 6 V.
