Subject :NSO    Class : Class 5

Ans 1:

Sohan R Jolapuri from Amanora School, Pune
Class : Class 5
Answer: The answer could be option B. Explanation: Assume the solar system as a circle, the sun as the radius( center) and the planets' orbits as the circumference( circle boundary). Mercury, with the least circumference length, revolves less distance than any other planet. This also means that it will take the least time to revolve around the Sun( 88 Earth Days ). Neptune, being the farthest of all planets, revolves more distance compared to others. Neptune takes the highest time to revolve( 165 Earth Years).[ Viewing the solar system Diagram would help.] Therefore, less the distance from the Sun, less the time taken to revolve; more the distance from the Sun, more the time taken to revolve.
