It may be more than 7K but with little bargaining you may get it i 7K in open market.
Q500 - 1GB RAM only Android Phone in your budget.
All others are 512 GB RAM Android Phones.
Micromax have 512 MB RAM in this price.
If you can increase budget You can get Micromax A77 for 7999/- with 1 GB RAM.
But Sony is best in your budget with good quality.
It has 512MB RAM in both above said models.
Iris 402 has 256 MB RAM only, hence not good choice in Android in your budget.
increase budget slightly and get Nokia Lumia 520. worth it than going for local brands. Else check Gionee P3 @ 7.1k. XOLO A500S is also worth checking.
