There's no denying that the MBA is a popular degree, but it isn't always the best choice for every career path or individual. It depends on you what interests you more getting technical knowledge, studying about science or managing things. It's you who will decide what is good for you. However you can do management studies after engineering as well.

Hi naveen,
       Engineering and business fields both offer great career opportunities. You should determine which field you personally prefer and go with it .
So, it is purely based on self interest.
If you are good in negotiating and relationships ,MBA would be a good career for you.
If you are good in designing ,coding, creating or innovation,then engineering is a great choice.
Otherwise , you can pursue graduation in engineering and post graduation in MBA.
Hope it helps .
