  1. Thanks a lots sir

  2. in question 26th the parrot suts on a bare high power line so why it doesn’t get a shock ?

  3. What’s the probability of these questions coming in exam?

    1. These questions are based on NCERT, and 1 to 2 questions can be asked in board exams.

  4. wire will have a insulating covering which will pevent parrot from schok

  5. Plz. Make this available as a PDF.

    It will be better to solve these questions as a practice paper..
