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.

b)100kg, because it is not one of the standard metric units of mass whereas all other options are. Standard prefixes of metric units include deca(10^1), hecto(10^2), kilo(10^3), mega(10^6), giga(10^9) etc. Since gram is the basic unit here,10^3 g(1kg),10^6 g(1000kg)... are standard metric units of mass.
if you don't mind, please explain it more clearly,
I think I made it look complicated... These are the standard metric units of mass and 100kg is not in them. You can find it on Googling.
And I am not sure if there's any more intelligible way to determine the odd one.🤞🏼
