hi saikumar ,

the fee in kkr is lower than the fee in annamacharya institite of technology . but the placements in annamacharya are very good comparitive to the knrr college . the highest pachake of placement in annamacharya is 8.5 lakh . annamacharya college is also accediated by the NAAC B . the knrr is an affiliated college but annamacharya college is autonomous . 

so , on the whole annamacharya institute is preferrable .

all the best
