Dude First off didn't you get any other decent topic to talk about? Second, that was the only thing you could think that souds absurd, in Mahabharat? Lastly, have you ever heard of Twins, triplets and quintuplets. If a mother gives birth to penta-tuplets (5 kids, whatever the term is) then she can finish that ration within 20 years. Okay that sounds difficult, but is a possible answer. 20 yrs difference between brothers ain't that bad.
