IIM

Absolutely you will get into top IIMs, provided you score pretty high percentile and able to crack GD/PI with precision.

Even the newest IIMs will stand miles ahead of ICFAI.

FMS is better as it has a low fee structure with good placement package. The fee structure of MBA in IIMs is very high.

Surely there is.
Ask your company to give you educational leave (Depending upon your company's policies) so that you can join the same company after completing your MBA in higher responsibility.

Hi,
The average package for IIM-Ahmedabad will be 23 LPA approx. same will be for Bangalore and Kolkata. For older IIM, still, you will get around 17 LPA, new IIMs like IIM-Shillong won't have 100% placement and the package will be around 8 LPA.

Hi,
There is a wide choice of institutes offering Executive MBA or PGPX programs apart from IIMs. You can aim to pursue it from the top notch B-schools like the Indian School of Business (ISB) Hyderabad, XLRI Jamshedpur, FMS Delhi, S.P Jain Institute of Management and Research, Mumbai, etc. You can plan your admission by checking out this list of Institutes offering Executive MBA programmes across India. You can sort them course-wise and city-wise to suit your requirement.

Class 10th and 12th percentage do matter as the top institutes like IIMs do check the overall profile of a candidate. If you have a valid reason like extracurricular or other certificate courses to defend your point of scoring less in academics than you can crack the interview and get selected.
Firstly, you need to score good in graduation and secondly score in the entrance examination. Doing so you have high chances of getting good colleges.
Hope it helps.
