its like due hyperconjugation teritary carbocation is stable.so it will lead to a unstable product but still it is prefered over primary one.so plz lemme know y is it so

There is a very nice review here

Page 4 and 5 have details.
Simply electrons from the sigma bonds on the adjacent carbons can overlap with the unoccupied p orbital of the carbocation. A primary carbocation has only one adjacent carbon a tertiary has three carbons providing stabilisation.

It has to do with the fact that tertiary carbocation has 3 methyl groups or other electron donating alkyl groups which compensates for the electron deficiency of the central C atom thus stablising the cation. This effect is not apparent in C-H bonds of primary carbocation because the bonding electrons are much closer to the hydrogen nucleus.

Well, what do you expect when a legend gets such a poor decision that goes against him! After all there wasn't even a great appeal? I think Dravid saw how preposterous the decision was & more so shocked to see the umpire raise his finger in utmost confidence. That's what made him explode. The umpiring in this IPL has been nothing short of mediocre especially for Indian umpires
