Hi Ankush,

Here is a trick for you so that you will not get confuse next time see, try to study first anti-markonikoff rule 

Anti = Aunty 

Aunty is stoping her son (hydrogen) not to go or to meet your friends i,e

Hyrdogen is positive charge so according to this it will go with negative charge. (Because his friend also positive charged ) 

Anti Markovnikov rule shows that hydrogen atom will attach to the carbon atom with the least hydrogen substituents.

Now, No Aunty is there 

Markovnikov rule shows that hydrogen atom will attach to the carbon atom with the most hydrogen substituents.

Hope you got your answer

Thanks for asking
